10. Find the subtended angle

Let the chord of the circle forms the base and the radii forms the equal sides of an isosceles triangle. If one of the base angle is 45\(^{\circ}\), then find the angle subtended by the chord at a point on the major and the minor arc.

 

Answer:

 

The angle subtended by the chord at a point on the major arc is \(^{\circ}\) and the minor arc is \(^{\circ}\).
