Read 3 integer numbers from the user; these numbers represent the lengths of 3 straight lines. From the 3 lengths, determine whether a triangle can be formed with the corresponding lines. If it is possible to form a triangle, determine whether the triangle is a right triangle or not. The rules to be used are: 1. To form a triangle where all lines’ ends meet (form vertices), the sum of the lengths of two sides must be greater than the length of the third side. This short video illustrates this concept: How to determine if the three sides make up a triangle. 2. Per the Pythagorean theorem: in a straight triangle, the square of the length of the longest side (the hypotenuse) is equal to the sum of the squares of the lengths of the other two sides. 3. The user can enter the lengths of each line in any order, i.e.: you may not assume that the first length is the longest or the smallest or the middle value.
Answer:
Written in Python
print("Enter three sides of a triangle: ")
length = []
for i in range(0,3):
inp = int(input(""))
length.append(inp)
length.sort()
if length[1]+length[2] > length[0] and length[0] + length[2] > length[1] and length[0] + length[1] > length[2]:
print("Triangle")
if length[2]**2 == length[0]**2 + length[1] **2:
print("Right Angled")
else:
print("Not Right Angled")
else:
print("Not Triangle")
Step-by-step explanation:
This line prompts user for sides of triangle
print("Enter three sides of a triangle: ")
This line declares an empty list
length = []
The following iteration gets user input
for i in range(0,3):
inp = int(input(""))
length.append(inp)
This line sorts user input
length.sort()
The following if condition checks if user input is triangle
if length[1]+length[2] > length[0] and length[0] + length[2] > length[1] and length[0] + length[1] > length[2]:
The following is executed is the if condition is true
print("Triangle")
The following if condition checks if user input forms a right angled triangle
if length[2]**2 == length[0]**2 + length[1] **2:
print("Right Angled")
else:
print("Not Right Angled")
This is executed if user input is not a triangle
else:

I Need to show the equations please, and show my work
Answer:
15
Step-by-step explanation:
since both equations are set with a right angle, the equation must be equal to 90 degrees. So you set the equation as
13+x+4x+2=90
add the x variables together and the constants separately
15+5x=90
then subtract 15 from both sides.
15+5x=90
-15 -15
5x=75
then divide 5 from both sides.
75/5= 15
so x is 15 :).
Answer:
It shows a 90° angle split into 2 separate angles so,
[tex]13 + x + 4x + 2 = 90\\\\5x + 15 = 90\\\\5x = 75\\\\x = 15[/tex]
Basically, the total angle measure of the given angles [90°, (13 + x)°, and (4x + 2°) equals 180°. Take away 90 from 180 and you get 90, then solve for x using what's left: 13 + x + 4x + 2 = 90. You get x = 15.

How do I write Domain and Range in inequality notation?
Answer:
Step-by-step explanation:To combine two intervals using inequality notation or set-builder notation, we use the word “or.” As we saw in earlier examples, we use the union symbol, \displaystyle \cup∪, to combine two unconnected intervals. For example, the union of the sets \displaystyle \left\{2,3,5\right\}{2,3,5} and \displaystyle \left\{4,6\right\}{4,6} is the set \displaystyle \left\{2,3,4,5,6\right\}{2,3,4,5,6}. It is the set of all elements that belong to one or the other (or both) of the original two sets. For sets with a finite number of elements like these, the elements do not have to be listed in ascending order of numerical value. If the original two sets have some elements in common, those elements should be listed only once in the union set. For sets of real numbers on intervals, another example of a union is

What is the equation of the line that is parallel to the line represented in the table and goes through the point (-10, -2)?
Answer:
y = -3/2x - 17
Step-by-step explanation:
First you need to find the slope, since the lines are parallel the slopes would be the same as points of the other line on the table. When finding the slope you get -3/2, when you have the slope you need to find the y-intercept or in other words in y=mx+b, the "b" in the equation. In order to find the y-intercept you have to plug in the values of the point (-10,-2) so then the equation would look like -2 = -3/2(-10) + b. Then you would solve for b. Then when you put the components together you get y = -3/2x - 17.

In the diagram below, the radii of the two concentric circles are 3 centimeters and 7 centimeters, respectively.
What is the area of the shaded region?
Answer:
125.6 cm²
Step-by-step explanation:
Area of the shaded region = area of larger circle - area of the smaller circle
Area of the smaller circle = πr²
π = 3.14, r = 3 cm
Area of smaller circle = 3.14*3² = 3.14*9 = 28.26 cm²
Area of larger circle = πr²
π = 3.14, r = 7
Area of larger circle = 3.14*7² = 3.14*49 = 153.86 cm²
Area of the shaded region = 153.86 - 28.26 = 125.6 cm²

Answer:
11. B 12. C 13. B
Step-by-step explanation:
11. Since segment MR bisects segment QO, side QP and side PO are equal. In the problem it states that angle MQP is congruent to angle ROP. The the angles QPM and OPR are vertical, so they are equal. That is enough evidence to conclude the answer.
12. ADC is bisected by BD, so that bisects AC too, which makes both sides equal. BD is perpendicular to AC, making right angles on both sides. The curves at angle A and angle C show that they are congruent. That should be enough evidence to show that it is congruent by ASA.
13. Triangle cannot be congruent by having the same angles, only similar since the lengths can be different. Congruent triangle means that the sides and angles are the same.

From the sum of 3x +4y -3xy and 5x +3y -2xy subtract the sum of 2x +y – 3xy and 10x -9y -8xy.
Answer:
-4x + 16y + 3xy
Step-by-step explanation:
The sum of 3x + 4y - 3xy and 5x + 3y - 2xy is 8x + 7y - 5xy.
The sum of 2x + y - 3xy and 10x - 9y - 8xy is 12x - 8y - 11xy.
Subtract the sum of the second pair from the first pair by changing the sign of the subtrahend. The result is -4x + 16y + 3xy

Complete Question
An analysis of several polls suggests that 60% of all Florida voters plan to vote for Anderson. A poll of 250 randomly selected Florida voters shows that 144 plan to vote for Anderson.
Required:
a. What is the probability of this result (i.e. 144 voters or less out of 250) happening by chance, assuming the aggregate poll model proportion of 60% is correct?
b. Does your result from part I indicate that the number of voters who plan to vote for Anderson has decreased? In other words, is this outcome unusual?(Recall that an unusual event has a probability of 0.05 or less of occurring )
Answer:
a
[tex]P(p < \^p) = 0.2206[/tex]
b
It is not an unusual event
Step-by-step explanation:
From the question we are told that
The population proportion is p = 0.60
The sample size is n = 250
The number that plans to vote for Anderson is k = 144
Generally the mean of the sampling distribution is
[tex]\mu _{x} = p = 0.60[/tex]
Generally the standard deviation is
[tex]\sigma = \sqrt{ \frac{p(1 - p )}{n} }[/tex]
=> [tex]\sigma = \sqrt{ \frac{0.60(1 - 0.60 )}{250} }[/tex]
=> [tex]\sigma = 0.0310[/tex]
Generally the sample proportion is mathematically represented as
[tex]\^{p} = \frac{k}{n}[/tex]
=> [tex]\^{p} = \frac{144}{250}[/tex]
=> [tex]\^{p} = 0.576 [/tex]
Gnerally the probability of this result (i.e. 144 voters or less out of 250) happening by chance, assuming the aggregate poll model proportion of 60% is correct is mathematically represented as
[tex]P(p < \^p) = P(\frac{ p - \mu_{x}}{ \sigma } < \frac{ \^ p - \mu_{x}}{ \sigma } )[/tex]
=> [tex]P(p < \^p) = P(Z < \frac{ 0.576 - 0,60}{ 0.0310} )[/tex]
=> [tex]P(p < \^p) = P(Z < -0.77 )[/tex]
From the z-table the probability of (Z < -0.77) is
[tex]P(Z < -0.77 ) = 0.2206[/tex]
So
[tex]P(p < \^p) = 0.2206[/tex]
Since
[tex]0.2206 > 0.05[/tex] it implies that it is not an unusual event
