Question

Use the given angle measures to find the indicated

Answer 1

Answer:

∠B = 116.4°

Step-by-step explanation:

1. If angle ∠B is a supplement of ∠A, that means they both add up to 180°.

2. Given that ∠A is 63.6°, we just have to subtract that from 180:

• $180-63.6$

• $116.4$  

Therefore, ∠B = 116.4°.

Answer 2

Answer:

m∠B = 116.4°

Step-by-step explanation:

Supplementary angles add up to 180°

190° - 63.6° = 116.4°

m∠B = 116.4°
