four times the complement of an angel is sixty-two less than twice the supplement of the angel
Answer provided by our tutors
let 'x' be the angel we are looking for.
by definition the complement of x is 90 - x
by definition the supplement of x is 180 - x
4*(90 - x) = 2*(180 - x) - 62
360 - 4x = 360 - 2x - 62
-4x + 2x = - 62
- 2x = - 62 multiply both sides by (-1/2)
x = 31
the angle is 31 degrees.
