Question

What is the measure of an angles whose measure is 40degree less then its Supplement​

Answer 1

Step-by-step explanation:

Assumption: Let the angle be x.

Therefore, its supplement = 180° - x

According to the question,

(180° - x) - x= 40°

=> 180° - x - x = 40°

=> 180° - 2x = 40°

=> -2x = -140°

=> -x = -140°/2

=> x = 70°
