50 POINTS!!!!!!

1. Angles A and B are supplementary. Determine the measure of angle A if the measure of angle B is 109.6°.

A) 250.4°
B) 63.2°
C) 70.4°
D) 19.6°

Answer 1

C. 70.4
180-109.6=70.4

Answer 2

• C) 70.4°

Explanation:

We know supplementary angles add up to 180°:

• A + B = 180°

Find the missing one:

• A + 109.6° = 180°
• A = 180° - 109.6°
• A = 70.4°

Correct choice is C.
