Question

An angle measures 27.8° less than the measure of its supplementary angle. What is the measure of each angle?

Answer 1

∠1 = 103.9° ; ∠2 = 27.8°

Explanation:

Supplementary angles = 180°

So, Let the angles be 'x'

Then, x + x -27.8° = 180°

2x - 27.8° = 180°

2x = 180° + 27.8°

2x = 207.8°

x = 207.8°/2

x = 103.9°

Therefore ∠1 = 103.9° ; ∠2 = 27.8°

I hope the answer is correct and has helped you!!!
