Question

find the measure of an angle is 7 times its complement is 10 less than three times its supplement

Answer 1

angle that is complement of itself is 45°. Complementary angles are those two angles whose sum is 90 degree.So , let's take an angle x. And the other angle be 90-x. x=90-x 2x=90 x=45 degree So 45 degree is the angle which is the MEASURE OF AN ANGLE WHICH IS COMPLEMENT OF ITSELF .
