Two angles of a triangle have the same measure and the third one is 27 degrees greater than the measure of each of the other two. Find the measure of the LARGEST angle in the triangle

Answer 1

2A + 27+A = 180 the 3 angles sum to 180 for any triangle

3A = 180-27 = 153

A = 153/3 = 51 degrees for two of the angles,

the third angle is 51+27 = 78 degrees = the largest angle
