Question 1006283
 The average of the measures of angle X, it's complementary angle, and it's supplementary angle is 80 degrees.
Find x
{{{((x + (90-x) + (180-x)))/3}}} = 80
multiply both sides by 3
x + (90-x) + (180-x) = 240
Combine like terms
x - x - x + 90 + 180 = 240
-x + 270 = 240
270 - 240 = x
30 = x
x = 30 degrees
:
What is the measure of the complement of angle X?
90 - 30 = 60 degrees
