Question 491447
what is the measure of an angle if twice the measure of its supplement is 30 more than five times the measure of its complement ?

-------
Let the angle be "x".
Then its supplement is "180-x"
And its complement is "90-x"
------
Equation:
2(180-x) = 5(90-x)+30
360 - 2x = 450 - 5x + 30
3x = 120
x = 40 degrees
