Question
In △ABC
, m∠A=63°
and m∠C=99°
. What is the measure of angle B
?(1 point)
m∠B =

°

Answer 1

In any triangle, the sum of the interior angles is always 180°.

Given:
- m∠A = 63°
- m∠C = 99°

We can find m∠B using the formula:

m∠B = 180° - m∠A - m∠C

Substituting the given values:

m∠B = 180° - 63° - 99°
m∠B = 180° - 162°
m∠B = 18°

So, m∠B = 18°.
