Question

A triangle has angles measuring 35° and 90°. What is the measure of the third angle?

Answer 1

55 degrees

Explanation:

All the angles of a triangle should add up to 180 degrees.

So, if you add angles 1 and 2 together and subtract them from 180 it will result in the unknown angle.

35+ 90 + x = 180

125 + x = 180

x = 55
