Some candidates chose to verify that the angle was 2.22 radians by again using the cosine rule to show that ZY was 9 cm. A small number of candidates worked in degrees and converted to radians at the end. Part (b) involved finding the area of the major sector XZWX but many candidates found the area …

Cosine rule: Use this formula to find a side length: Use this formula to find an angle: Use the cosine rule if you know all 3 sides (to find an angle) OR. if you know 2 sides and the angle in between (to find the 3rd side). In other situations try using the sine rule. Area of a triangle is A = Properties of sin, cos and tan Solving Equations
