Angle a and angle b are supplementary. the measure of angle b is 15∘ less than the measure of angle a. what is the measure of angle b, in degrees?

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°

answer: y = 3/2 x - 3

y = 1/8 x - 3/4 that would be your correct option
