Question

If the angle of a minor sector of a circle is ${120}^{\circ }$, then the major sector will have an angle of ____.

• A. ${120}^{\circ }$
• B. ${240}^{\circ }$
• C. ${60}^{\circ }$
• D. ${180}^{\circ }$

Answer 1

The correct option is B

${240}^{\circ }$

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