Question 780005
If four times the supplement of an angle is added to eight times the angle's complement, the sum is equivalent to three straight angles. Find the measure of the angle that is supplementary to the complement.
-----
angle:: x
complement:: 90-x
supplement::1 180-x
------------------------------
Equation:
4(180-x) + 8(90-x) = 3*180
-------
720-4x + 720-8x = 620
1440-12x = 620
12x = 820
x = 68 1/3 degrees
-------
The complement is 21 2/3 degrees
----
The supplement of this complemet is 158 1/3  degrees
