प्रश्न
In a circle with centre O, the measure of a minor arc is 110°. What is the measure of the major arc PYQ?
उत्तर
Suppose PQ is the minor arc and then m(arc PQ) = 110°.
We know that, measure of major arc = 360° − measure of the corresponding minor arc.
∴ m(arc PYQ) = 360° − m(arc PQ)
= 360° − 110°
= 250°
Hence, the measure of major arc PYQ is 250°.
