Figure 6 shows the triangle ABC, with all side lengths measured in centimetres. 14.6 cm 21.4 cm B 7.5 cm Figure 6 (i) Find ABC, giving your answer correct to the nearest degree. (ii) Find the area of triangle ABC, giving your answer correct to the nearest square centimetre. (i) Convert 35 to radians, leaving your answer in terms of . (ii) Use your answer from part (d)(i) to find the perimeter of a sector between a circle of radius 5 cm and another circle of radius 10 cm determined by an angle a of 35 the sector is outlined in a solid black line in Figure 7. Give your answer correct to three significant figures.
