Solve the problem.An isosceles triangle contains two angles of the same measure. If the measure of the third angle is 51° less than the measure of either of the other two angles, find the measure of one of the identical angles by solving the equation 2x + (x - 51) = 180, where x represents the measure of one of the identical angles.
