3a+4 ,4a-5 if the pairs of angles are complementary ,find the measure .
In a triangle two angles are complementary when they combine to make a right angle. So now answer the following question---how many degrees in a right angle? Then add thse two angles to the nubber of degrees in a right angle.
You should end up with an elementary algebraic equation with a single unknown--rearrange to solve for that unknown.
