Question

Which of the following angles is/are acute?

• A. ${90}^{\circ }$
• B. ${10}^{\circ }$
• C. ${120}^{\circ }$
• D. ${60}^{\circ }$.

Answer 1

Answer: (B), (D)

The correct options are
B

${10}^{\circ }$

D

${60}^{\circ }$.

Acute angles are angles less than ${90}^{\circ }$.

A right angle measures exactly ${90}^{\circ }$.

So, ${10}^{\circ }$ and ${60}^{\circ }$ are acute angles.
