The sum of the measures of the angles of all triangles is 180 degrees. If one angle of the triangle measures 45 degrees, and the
other two angles are equal, what is the measure of each of the other two angles? Choose the equation that represents the situation. Let "a" represent the unknown angle measurement. A. 2 + a + 45 = 180
B. 2a + 45 = 180
C. 45a + 2 = 180
