Answer:
75
Step-by-step explanation:
they gave u 105 it is parallel to the line above it so u add them
105+105=210
then u subtract with 360 which forms a full angle
then u get 150
now u got the total of 2 angles so u divide them with2 to get 1 angle
then the answer is going to be 75

The diagram shows a right angled triangle.

Answers
Answer:
6 root 2
Step-by-step explanation:
Pythagous Therom
A^2 = B^2 + C^2
B^2 = C^2 - A^2
B^2 = 36 - (2 Root 3)^2
B^2 = 24
B = 2 root 6
Base x Height / 2 for area of Triangle
2 root 3 x root 24 = 12 root 2
12 root 2 / 2 = 6 root 2
The right triangle is the one where one of the angles is a right angle (90 degrees) or two of the sides are perpendicular.
Finding the value of k:The right-angled triangle is one where one of the angles is equal to 90°. The sum of the other 2 aspects is 90°. The perpendicular and the base of the triangle are indeed the sides that include the right angle. The hypotenuse, which would be the longest of the three sides, is the third side.In [tex]\Delta[/tex] ABC
h² = 6² -(2√3)²
h² = 36-2² × √3²
h² = 36- 4× 3
h² = 36- 12
h² = 24
h =√24
h = 2√6 cm
Area = [tex]\frac{1}{2}[/tex]× BC × h
= [tex]\frac{1}{2}[/tex] × 2√3 × 2√6
= 2√18
= 6√2
compare it with A= K√2 So K= 6

Step-by-step explanation:
For the function y = f(x), a reflection in the y axis is y= f(-x)
(-x)^3 = -x^3 so negate that term
(-x)^2 = x^2 so leave that as is
(-x)^1 = -x so negate that term too
What's substitution for y=4x-1, 2x+y=5
Answers
Step-by-step explanation:
y = 4x-1
2x+y = 5
2x+(4x-1) = 5
6x - 1 = 5
6x = 6
x = 1
Answer:
(1,3)
Step-by-step explanation:
Since we already have the variable to it self, we can substitute y=4x-1 into 2x+y=5.
So it would be 2x+(4x-1)=5
Remove the parentheses
Combine like terms
Move the constant to the right
Divide 6 on both sides to get the variable by it self.
x=1
Then we substitute x=1 into y=4x-1, so..
y=4(1)-1
y=4-1
y=3
So the answer would be (1,3).

which equation would be the easiest to solve first by using the substitution method? EXPLAIN WHY
equation 1: 3x+5y= -8
equation 2: x- 2y=1
Answers
Answer:
Equation 2: x - 2y = 1
Step-by-step explanation:
The equations easiest to use substitution are the ones that have the variable multiplied by one, as in the case of Eq. 2 where x is 1x, so if you substitute a zero for x, we know that y has to be -1/2 for the equation to be true. Furthermore, if you substitute a 0 for y you automatically know that x = 1.
If you try to substitute anything for x in equation 1, let's say x = 1, you still have to multipy by 3, then the rest of the problem would be more steps.

At Norman's Newsstand, 5 magazines cost $20.00. How many magazines could you buy with $44.00?
Answers
Answer: 11 magazines
Step-by-step explanation:
1) 20/5 = $4 per magazine
2) 44/4 = 11 magazines
Answer:
10 magazines
Step-by-step explanation:
5 magazines cost $20.00
You have $44.00
If 5 magazines cost $20.00
Then 10 magazines would cost $40.00
Since the maximum amount of money you can spend is $44.00, you can only buy 10 magazines for $40.00 and be left with $4.00.

Elle and Layla are collecting data on student use of the school library. They collect data samples from the same population of students. After collecting their data, they each determine the standard deviation for their data sets. Layla's standard deviation is much larger than the standard deviation from Elle's data set.
Answers
Answer:
Layla's data set has a greater spread than Elle's data set
Eplanation:
I just got it right on the test I took..
The conclusion is Layla’s data set has more outliers or extreme values than Elle’s data set.
What do you mean by standard deviation?In statistics, Standard deviation is a measure of the variation of a set of values.
σ = standard deviation of population
N = number of observation of population
X = mean
μ = population mean
We are given that;
E and L collect data on library use from same students. L’s SD > E’s SD.
Now,
Since Elle and Layla collected data samples from the same population of students, we can assume that they have the same mean for their data sets. Hence, if Layla’s standard deviation is much larger than Elle’s standard deviation, it means that Layla’s data set has more variation or dispersion than Elle’s data set. In other words, Layla’s data set has more outliers or extreme values than Elle’s data set. This could be due to random sampling error or some other factor that influenced Layla’s data collection.
Therefore, by the standard deviation the answer will be Layla’s data set has more outliers or extreme values than Elle’s data set.

Which set of side lengths cannot form a triangle? (screen shot attached)
Answers
Answer:

Step-by-step explanation:
Based on the Triangle Inequality Theorem that states that the sum of any 2 sides of a triangle must be greater than the measure of the third side, we can find what set of lengths cannot form a triangle.
The only set that does not follow the theorem is the set with lengths 7in, 7in, and 15in. It does not follow the theorem because...
7 + 7 < 15 (which should not be true based on the theorem)

Determine the length of AC and DE, and the value of x.
Answers
Answer:
n = 16, AC = 60, DE = 30
Step-by-step explanation:
DE joins the midpoints of 2 sides of the triangle and is half the length of the third side, that is
DE = [tex]\frac{1}{2}[/tex] AC , substitute values
n + 14 = [tex]\frac{1}{2}[/tex] (3n + 12) ← multiply both sides by 2 to clear the fraction
2n + 28 = 3n + 12 ( subtract 2n from both sides )
28 = n + 12 ( subtract 12 from both sides )
16 = n
Then
AC = 3n + 12 = 3(16) + 12 = 48 + 12 = 60
DE = n + 14 = 16 + 14 = 30
