In the figure, PC represents a vertical object of height h cm. From a point A, south of C, the angle of elevation of P is a. From a point B, 400 cm east of A, the angle of elevation of P is B. AC and BC are x cm and y em respectively. a.) Express x in terms of h and a b.) Express y in terms of h and B c.) If a = 60° and B = 30°, find the value of h correct to 3 significant figures.
