Question

One angle is 13 less than five times of another angle. The sun of the measures of two angles is 140 degrees . determine the measure of each angle in degrees

Answer 1

We have x + y = 140 degrees and x = 5y - 13 ;
Then, 5y - 13 + y = 140;
6y - 13 = 140;
6y = 153;
y = 153 ÷ 6;
y = 25.5 degrees;
x = 140 - 25.5;
x = 114.5 degrees;
