Question

Mabel measured an angle on her math worksheet with her protractor. The angle measured 73°. If she were to draw an angle which was supplementary to the angle on her worksheet, what should that new angle measure?

Answer 1

Since supplementary angles add up to 180°, the new angle that Mabel should draw would measure:

180° - 73° = 107°

So, the new angle should measure 107°.
