Answer:
The answer to your question is B = 82.5°
Step-by-step explanation:
Data
A and B are supplementary angles
A = x
B = x - 15°
Process
1.- Write and equation to solve this problem. As these angles are supplementary the sum equals 180°.
A + B = 180°
2.- Substitution
x + x - 15 = 180
3.- Solve for x
2x = 180 + 15
2x = 195
x = 195 / 2
x = 97.5
4.- Find the measure of angle B
B = x - 15
B = 97.5 - 15
B = 82.5°
Round each and multiply.
53 rounds down to 50,
39 rounds up to 40.
50*40=2000.
This is close to the actual answer, which is 2067.
