An isosceles triangle includes two angles that measure 60' which equation can be used to find the measure of the third angle

CX=180-2(60)

DX=180+2(60)

The answer is C. since a triangle has to have a total of 180 degrees, you have to add both of the degrees of both the angles. 60 + 60= 120.
180-120=60
Your last angle is 60 degrees.
