In a triangle, the measure of the first angle is three times the measure of the second angle. the measure of the third angle is 55 more than the measure of the second angle. use the fact that the sum of the measures of the three angles is 180 to find the measure of each angle to find the measure of each angle.

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103
