An angle measures 64° more than the measure of a complementary angle. What is the measure of each angle?
GarryVolchara [31]
Complementary angles are 90 degrees,so if the angle is 64 degrees more,you just only have to add 90+64=154.

The measure of the angle is 154 degrees

Hope i helped.

Remember:complimentary angles add up to 90 while supplementary angles add up to 180.
