The supplement of an acute angle is a/an __________ angle.

• A. Acute
• B. Obtuse
• C. Right
• D. Straight

Answer 1

Answer: (B)

Obtuse

We know acute angle $<{90}^{\circ }$

Let us take an example.

$\angle x={45}^{\circ }$ .....$x$ is an acute angle

Supplement of $x$ is

${180}^{\circ }-{45}^{\circ }={135}^{\circ }$ ....it is an Obtuse angle

Obtuse angle $>{90}^{\circ }$.
