Question

In right triangle ∆ABC, ∠A = 42°. Find the measure of ∠B which is the other non right angle.

Answer 1

Answer:

48 degrees

Step-by-step explanation:

A triangle has three angles that add up to 180 degrees. In a right triangle, one of the angles in 90 degress, and the other 2 add up to 90. In this case, we have 2 given angles, 90 degree angle and 42 degree angle. If we do 90+42 it gives us 132. We then subtract that from 180 to give us 48 degrees.
