let the angle be x
complement=90-x
supplement=180-x
supplement of the complement=(180-(90-x))
So, 2(180-(90-x))=60+180-x
2(180-90+x)=240-x
360-180+2x=240-x
3x=240-360+180
3x=60
x=20 degrees
Check:
compliment (20)=70
suppliment (20)=160
suppliment of compliment (70)=110
2*110=60+160
220=220

First, let's find the angle, which we can call angle A, then we can find its complement (90-A) to answer the problem.
The supplement of A is 180-A and the complement of A is 90-A
From the problem description, we can write:
2(180-(90-A)) = (180-A)+60 Simplify this and solve for A
2(180-90+A) = 180+60-A
2(90+A) = 240-A
180+2A = 240-A Add A to both sides of the equation.
180+3A = 240 Now subtract 240 from both sides.
3A = 60 Finally, divide both sides by 3.
A = 20 degrees. Now we can find the complement of A (90-A) as required by the problem.
90-A = 90-20 = 70 degrees.
The solution is:
The complement of the angle is 70 degrees.
