Consider the diagram of supplementary angles.

Question

What is the value of x?

Responses
A 132°
B 28.5°
C 16.5°
D 12°

48° 8x

Answer 1

The correct answer is C) 16.5°.

Since the angles are supplementary, their measures add up to 180°.

So, we have x + 48° = 180°.

Subtracting 48° from both sides gives x = 132°.

Therefore, the value of x is 132°, which corresponds with answer choice A.
