Question 80
The supplement of an angle is $$15^\circ$$ more than three times its complement. The measure of the angle is:
Solution
Supplement of angle =180 -x and complement of angle =90-x
$$180-x=3(90-x) +15$$
$$165-x=270-3x$$
$$-x +3x=270-165Â $$
$$2x=105$$
$$X=\frac{105}{2}$$
$$X=52.5^\circ$$
Option B is correct.
