Question

The supplement of an angle is 3 times the complement of an angle. Find half of the complement of the angle.

Answer 1

Let the angle be x and the compliment of that angle be y.
Sum of complimentary angles=90
x+y=90
x=90-y
Let the supplement of x be z.
z=3y
Sum of supplementary angles=180
x+z=180
x+3y=180
90-y+3y=180
Can u find y?
