Question

In the figure, m (arcAXB)=120. ANGLE ABC intercets arc AXB then what is line DC with respect to the circle? Give your reason.​

Answer 1

Answer:

Measure of major arc = 360° – measure of corresponding minor arc ∴ m (arc AYB) = 360 – m (arc AXB) ∴ m (arc AYB) = 360 – 120 ∴ m (arc AYB) = 240°
