Question

angleA and angleB are supplements of each other if m angle B =(X+40°) find m angleA?​

Answer 1

Answer:

Step-by-step explanation:

Given that,

∠A and ∠B are supplements of each other and

m∠B = ( x + 40°)

We know that, the sum of the supplementary angles are equal to 180°.

∴ x + 40° = 180°

x = 180° - 40°

x = 140°

∴m∠A = 140°

Answer 2

question:

Find the supplement of each of the following:

(1) 70°

(2) 99°

(3) 110°

answer:

(1) 70° = 180 - 70 = 110

(2) 99° =180 -99 = 81

(3) 110 = 180 - = 70
