Answer:
Sum of the opposite pair of a cyclic quadrilateral is 180°.
c= 180-102= 78°
c= 180-102= 78°d= 180-92= 88°
intercepted arc
=>2(102°)= 140+a°
a=64°
Simillarly
=> 2(d°)= a°+b°
b°= 112°
so ....
a=64°
a=64°b=112°
a=64°b=112°c=78°
a=64°b=112°c=78°d=88
hope it helps you ....

Tyler is observing the ascent of a steel beam being lifted by a crane from a position about 250 ft away. What trigonometric function models the height h in feet of the beam as a function of the angle of inclination θ from Tyler's position to the steel beam
Answers
Answer: [tex]h=250 \tan \theta[/tex]
Step-by-step explanation:
Given
Tyler is 250 ft away from the crane
The angle of inclination is [tex]\theta[/tex]
Using the figure, we can write heigh h as
[tex]\Rightarrow \tan \theta =\dfrac{h}{250}\\\\\Rightarrow h=250\tan \theta[/tex]
A rectangular basketball court is in the center of a larger rectangular field. The basketball court measures (9x + 4) ft long and 5x ft wide. The field measures (11x + 4) ft long and 7x ft wide. What is the area of the field that is not covered by the basketball court?
Answers
Answer:
2(11x+4)+2(7x)=(22x+8)*14x=308x^{2}+112x
2(9x+4)+2(5x)=(18x+8)*10x=180x^{2}+80x
308x^{2}+112x-180x^{2}-80x=128x^{2}+32x- the area that is not covered

PLS SHOW YOUR WORK
Answers
Answer:
Isaac's total bill is $84.53
Step-by-step explanation:
$37.00 + $42.00 = $79.00 < b (bill)
b + t (sales tax) = c (total cost)
(7%/100 = 0.07)
(0.07 * 79 = 5.53)
(t = $5.53)
$79.00 + $5.53 = $84.53

Answer:
The answer is "13".
Step-by-step explanation:
Euler method=e=0.2 constantly binding the error
Precision should be 9 decimal places=0.000000001
The number of steps should be n.
In order to guarantee precision,
[tex]\to 0.2^n> 0.000000001\\\\ \to n> \frac{\log(0.000000001) }{\log(0.2)} \\\\ \to 12.876 \approx 13[/tex]

Answer:
x = -6 (correct answer)
mistakes were made in Step 2 and Step 5.
Step-by-step explanation:
The mistake is made in Step 2, application of the distributive property. This is often a source of error. Here, the error is in signs.
Step 1: 12 = -2(x -4) -8
Step 2: 12 = -2x +8 -8 . . . . . . the correct step 2
Step 3: 12 = -2x . . . . . . . . . . . like terms combined
Step 4: -6 = x . . . . . . . . . . . . . divide by -2
__
Check
12 = -2(-6 -4) -8 = -2(-10) -8 = 20 -8 = 12 . . . . answer checks OK
__
Comment on other mistake
In the original Step 5, -2 was divided on the right and added on the left. This is a violation of the properties of equality, so guarantees a wrong answer. The same operation must be performed on both sides of the equation.
An additional mistake was made in that the answer was not checked.
Chris has 7/8 yards of purple ribbon and one whole one over 6 yards of ribbon Chris has a total of three holes to over 3 yards of ribbon how many yards of Chris's ribbon are neither purple nor green
Answers
Complete question :
Chris has 7/8 yards of purple ribbon and 1 1/6 yards of green ribbon. Chris has a total of 3 2/3 yards of ribbon. How many yards of Chris's ribbon are neither purple nor green.
Answer:
1.625 yards
Step-by-step explanation:
Purple ribbon = 7/8 yards
Green ribbon = 1 1/6 yards = 7/6 yards
Total ribbon = 3 2/3 yards = 11/3 yards
Ribbon that is neither purple nor green :
Total ribbon - (green + purple ribbon)
7/8 - (7/6 + 7/8)
11/3 - (28 + 21) / 24
11/3 - 49/24
= 1.625 yards

Complete question :
You randomly choose a tile. Without replacing the first tile, you choose a second tile. Find the probability of the compound event. Write your answer as a fraction or percent rounded to the nearest tenth. The probability of choosing two even numbers is
Tiles : 7,6, 5, 8, 9, 10, 20
Answer:
2 /7
Step-by-step explanation:
The probability of a compound event in the scenario described above :
P(1st pick) * p(second pick)
Recall: this event is without replacement
P(choosing two even numbers)
Probability = required outcome / Total possible outcomes
Required outcome = even Number tiles = (6, 8, 10, 20) = 4
Total possible outcomes = number of tiles = 7
P(even number on first pick) = 4/7
P(even on second pick) = 3 / 6 = 1/2
P(compound event) = 4/7 * 1 /2 = 4 /14 = 2 /7

(kels and emily... PLZ DONT ANSWER!!)
Answers
Answer:
The Pythagorean theorem used in right-angled (equilateral) triangles is a relationship between the sides of a right-angled triangle, where the sum of the square of the legs is equal to the square of the hypotenuse.
If a and b are legs, and c is the hypotenuse, then
a2 + b2 = c2.
Because the triangle is right angled, there is no greater side length in the triangle, so an unlimited number of Pythagorean positions can be produced by flipping the sides.
