In a triangle, one angle is twice the measure of the second angle. The third angle is three times the measure of the second angle. Find the measure of eah angle.
Since the angles are all compared to the second angle, let x (also known as 1x)= 2nd angle; therefore first angle which is twice the second = 2x and the third angle which is three times the second = 3x. All angles of a triangle have a sum of 180 degrees.
1x + 2x + 3x = 180
now combine like terms and equation solve for x.
