Question

Two angles are supplementary and one angle is 10 degree less than four times the other. Find the angles.
​

Answer 1

Answer:

142°, 38°

Step-by-step explanation:

Supplementary angles = 180°

So let one of the angle be = x

and BTP the another angle = 4x-10°

so, 4x-10° + x = 180°

5x = 190°

x = ¹⁹⁰/5

x = 38°

4x - 10° = 152° - 10°

= 142°

The angles are 142° and 38° (Ans.)
