Question 4:
- Diagram: Shows a circle with center O. APQ is a circumcircle. The chord AP subtends an angle of (110^\circ) at the center O of the circle. Angles (x^\circ) and (y^\circ) are indicated.
- Parts:
- a) Calculate the values of the angles (x^\circ) and (y^\circ).
- b) State the relationship between angles (\angle AQP) and (\angle AOP).
- c) The length of the radius, OA is 5cm. Calculate the area of triangle AOP.
Question 5:
