Question

Two Angles of a Triangle 53 and 68.What is the Measure of the Third angle?

Answer 1

The correct answer is answer choice A, 59. The sum of the three angles of a triangle is always 180°, so, if you have two angles, all you have to do is subtract them from 180 to get the thirds angle.

180 - 53 - 68 = 59
The third angle is 59°. 

Hope this helps!
