# If the measure of an angle is 23°17′18′′, what is the measure of its supplement? Question
Non-right triangles and trigonometry If the measure of an angle is 23°17′18′′, what is the measure of its supplement? 2021-03-07
Two supplementary angles have angle measures having a sum of 180°. So, the other angle can be found by subtracting the given angle from 180°:
180°−23°17′18′′=179°59′60′′°−23°17′18′′=156°42′42′′
