Question

A triangle has angles the mearsure 53 degrees and 66 degrees. What is the measure of the third angle?

Answer 1

The Answer Is 61. The Way We Figure That Out Is First, Add The Two Known Values Together. 66+53 = 119. Next, We Remember That A Triangle's Angles Must All Add Up To 180. So, 180-119 = Our Now Known Angle Of 61. I Hope This Helps!
