Question

plz answer this MCQ ​

Answer 1

Answer:

option (c) 15°

Step-by-step explanation:

Supplementary Angles are angles that add up to 180°.

So if ∠P and ∠Q are supplementary,

∠P + ∠Q = 180

∠Q = 3∠P

∠P + 3∠P = 180°

4∠P = 180°

∠P = 180° / 4

∠P = 45°

∠P = 3x

3x = 45°

x = 45° / 3

x = 15°

So, option (c) 15° is correct.
