Question

If an angle measures ${60}^{\circ }$, its complementary angle will measure.

• A. ${60}^{\circ }$
• B. ${120}^{\circ }$
• C. ${30}^{\circ }$

Answer 1

The correct option is C ${30}^{\circ }$

Complementary angles add upto ${90}^{\circ }$.
Hence if one angle = ${60}^{\circ }$, the other will be = ${90}^{\circ }-{60}^{\circ }={30}^{\circ }$
