ten less than three times the complement of an angle is it supplement.
find the measure of the supplement?

Write that as an equation. Let x be "the angle", so 180 x will be the supplement.
The complement of x is 90x
Your statement can be written:
3*(90  x) 10 = 180  x
Now solve that.
260 3x = 180  x
2x = 80
x = 40
So, what is the supplement of x? 
supplement of x is 140?
