Answer :

67.5 degrees

Let the measure of two equal angles of the triangles is x.

Thus, the angles of the triangles are x, x and 45 degrees.

The sum of the measures of the angles of all triangles is 180 degrees.

Hence, the equation is

x + x + 45 = 180

Solve the equation for x

2x + 45 = 180

2x = 180 - 45

2x = 135

x = 67.5

Therefore, measure of other two angles are 67.5 degrees.
