Question

What is the value of y? Enter your answer in the box. A triangle with angle measures thirty-seven degrees and seventy-nine degrees. The third angle has an unknown measure, y degrees.

Answer 1

180-(37+79)= 64 degrees

Answer 2

a triangle equals a total of 180 degrees, so if you add both degrees together: 37+79= 116, then minus 180, you will get the last angle.
180-116= 64 degrees, therefore
y=64 degrees
