For any triangle, the sum of the measure of the three angles equals 180°. Two of the angles have the same measure, a, and the third angle measures 45°. Which of the following equations could be used to determine the measure of a? 2(a+ 45) = 180 %3D А. В. a+ 45 = 180 %3D 2a - 45 180 %3D С. 2a + 45 = 180 %3D D.
