Two angles of a triangle have the same measure and the third one is 45 degrees greater than the measure of each of the other two. find the measure of the largest angle

90

Step-by-step explanation:

Let x be the measure of the first angle , this means that x will be the measure of the second angle and x + 45 will be the measure of the third angle.

The sum of interior angle of a triangle = 180 , that is

x + x + x + 45 = 180

3x + 45 = 180

3x = 180 - 45

3x = 135

x = 135/3

x = 45

Therefore the largest angle = 45 +45 =90
