Question
The measure of the two times of supplement of an angle
is 40° less than 7 times the measure of the complement of the same angle. Find the measures of the angle.Solution
Let angle be x So ATQ, 2(180 - x) = 7(90 - x) - 40 or 360 - 2x = 630 - 7x - 40 or 5x = 630 - 360 - 40 = 58or x = (230/5)° = 46°Â
