five times the complement of an angle less twice the angle's supplement is 40 degrees. find the measure of the supplement.
---------------
Let the angle be "x".
Its complement is "90-x"
Its supplement is "180-x"
-------------------
EQUATION:
5(90-x)-2(180-x) = 40
Solve for x

5(90-X)-2(180-X)=40
450X-5X-360+2X=40
-3X=40-450+360
-3X=-50
X=-50/-3
X=16.667 ANSWER.
PROOF
5(90-16.667)-2(180-16.667)=40
450-83.333-360+33.33=40
450+33.333-360-83.333=40
483.333-443.333=40
40=40
