To find the measure of angle B in △ABC, we can use the fact that the sum of the angles in a triangle is always 180°.
Given that:
m<A = 63°
m<C = 99°
We can find the measure of angle B by subtracting the sum of angles A and C from 180°:
m<B = 180° - (63° + 99°)
m<B = 180° - 162°
m<B = 18°
Therefore, the measure of angle B in △ABC is 18°.
In △ABC, m<A = 63° and m<C = 99° . what is the measure of angle B?
