The measure of one angle is twelve less than two times the measure of another angle. The sum of the measures of the two angles is 130 degrees. Determine the measure of each angle in degrees

Answer 1

x = angle 1

2x - 12 = angle 2

sum is 130

so x + (2x - 12) = 130

3x - 12 = 130

3x = 142

x = 47.33

2x - 12 = 2(47.33) - 12 = 82.67
