Question

What is relationship between ∠a and ∠b ?​

Answer 1

Step-by-step explanation:

XY is a straight so sum of angles is 180°.

<POY = 90° (given)

So , <a + <b + <POY = 180°

<a + <b + 90 = 180°

Therefore <a + <b = 90°

Hence <a and <b are complementary angles as their sum is 90°.

Hope it helps.
