If you have a 43 degree angle, what is the measurement of the angle which is supplementary to it?

Step-by-step explanation:

x+43=180

x=180-43=137°

137°

Step-by-step explanation:

Supplementary angles are next to each other on a straight line. Therefor, if you add them, the sum of the angles is 180°. We can use this to find the measure of the missing angle.

180° - 43° = 137°

The missing angle is 137°
