Question

If the angle of major sector in a circle is ${240}^{\circ }$, the angle of minor sector will be ______.

• A. ${120}^{\circ }$
• B. ${110}^{\circ }$
• C. ${100}^{\circ }$
• D. ${140}^{\circ }$

Answer 1

The correct option is A

${120}^{\circ }$

Angle made by a circle $={360}^{\circ }$
Major sector angle $={240}^{\circ }$
Therefore, minor sector angle $=360-240={120}^{\circ }$
