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

B

Step-by-step explanation:

2a+45=180

subtract 45 from both sides which equals 2a=135

divide both sides by 2 which would solve for a.
