Two angles are complementary. The measure of the smaller angle is five less than the measure of the larger angle.  What is the measure of the smaller angle?

We have that

 

x + ( x - 5)  =  90

 

2x - 5  =  90            add 5 to both sides

 

2x  =  95    divide both sides by 2

 

x =  47/5°

 

And the smaller  angle  is    47.5 - 5  =  42.5°

90 = 45 + 45 = ( 45 + 2.5 ) + ( 45 - 2.5 ) = 47.5 + 42.5 = 90  laugh
