Question

c) angle A and angle B are supplementary angles. If angle B is five times angle A, find the measure of
both the angles.​

Answer 1

Step-by-step explanation:

angle B = 5(angle A)

angle A + angle B = 180°

angle A + 5(angle A) = 180°. (substituting the value of angle B)

6( angle A) = 180°

angle A = 30°

angle B = 150°

Answer 2

Step-by-step explanation:

let the both angle be 5x and x.

A.T.Q

= 5x + x = 180 (supplementary is 180°)

= 6x =180

= x = 180/6

= x = 30

a angle= 30°

b angle = 30×5 =150°
