Question

If the angles subtented by a minor arc is 30 degree, then what is the angle subtended by the major arc?

• A. ${360}^{\circ }$
• B. ${330}^{\circ }$
• C. ${300}^{\circ }$
• D. ${270}^{\circ }$

Answer 1

The correct option is B ${330}^{\circ }$

Total angle subtended by a circle = ${360}^{\circ }$. If the minor arc subtends an angle of ${30}^{\circ }$, then the major arc subtends ${360}^{\circ }-{30}^{\circ }={330}^{\circ }$.
