Question

In a triangle, two of the angles measure 78° and 49°. Find the measure of the third angle.

Answer 1

well all three sides of a triangle added up equals 180 degrees so 78 + 49=127 so 180 - 127 = 53 degrees so the answer to this question is 53 degrees

Answer 2

sum of interior angles of a triangle = 180
so
third angle = 180 - 78 - 49 = 53
