Answer 1

Hi...☺

Here is your answer...✌
===============================

Let the angle be 'x'

Then it's supplement = 180° - x

Now,

According to the question,

x = 180°-x

x + x = 180°

2x = 180°

x = 90°

HENCE,

Answer : 90°

Answer 2

Sum of supplementary angles = 180°

∴ x + x = 180°

2x = 180°

x = 180/2 = 90°
