put this solution on YOUR website! Two complementary angles are angles whose sum is 90, so add your two angles together, set them equal to 90 and solve.
( 12q - 9 ) + ( 8q + 14 ) = 90
Combine like Terms: 20q + 5 = 90
Subtract 5 from both sides: 20q = 85
Divide both sides by 20:
So your angle is
or
or 4.25 degrees
