What is the measure of ∠B given that ∠A measures 48°?

Answer 1

The measure of ∠B can be found by using the fact that the sum of the angles in a triangle is always 180°. Therefore, if ∠A measures 48°, then the sum of ∠A and ∠B must equal 180°.

∠A + ∠B = 180°
48° + ∠B = 180°
∠B = 180° - 48°
∠B = 132°

Therefore, the measure of ∠B is 132°.
