Question

In a triangle, the measure of the first angle is twice the measure of the second angle. The measure of the third angle is 68 more than the measure of the second angle. Use the fact that the sum of the measure of the three angles of a triangle is 180 to find the measure of each angle.

Answer 1

(2x) + (x) + (x + 68) = 180
4x + 68 = 180
4x = 112
x = 28

so the angles are 28, 56, and 96.
