Im in honors geometry and im stumped on this one question.
The supplement of an angle is 60 degrees lass than twice the supplement of the complement of the angles. Find the measure of the complement. The answer is 70 but I dont know how to get it.
What set up or equation should I use? like 2x +5= 15; x=5

x = angle
180 - x = supplementary angle
90 - x = complementary angle
180 - (90 - x) = 90 + x = supplement of complement
supplement = 2 (supplement of complement) - 60
180 - x = 2(90 + x) - 60
180 - x = 120 + 2x
60 = 3x
x = 20,
so complement = 90 - x = 90 -20 = 70

Angle equals X.
Supplement of X = 180-X
Complement of X= 90-X
Supplement of complement= 180 -(90-x)= 90+X
Therefore, 180-X = 2(90+X)-60
180-X=180+2X-60
60=3X
X=20
Complement=90-20=70
