measure

find the measure of an angle if five times the complement  of this angle is 150degrees greater than the supplement of the angle.

ok this question came form my lil sis.....meaning cousin

she said.
angle * 5 = 150
150 / 5 = 30
30 equals angle........

Re: measure

Let's call the angle X.   The complement angle would be equal to 90 - X and the supplement would be 180 - X.  If I understand you correctly:

5*(90-x) = 180 - X + 150

450 - 5X = 30 - X

4X = 420 

X = 105   

That means the angle is an obtuse angel (90 < x < 180) and I don't think obtuse angle have complementary angles.
