CD is a light house of height h, from where adjudicators observe a race between sailboats. A and B are two buoys which lie on a route to be followed by the sailboats. From D the angle of depression to A is B and CÂB = 0 = . D is 5.76 meters above the water level, AB = x and BC = y. 4.1 If x = 30 m and y 25 m, determine sin(ACB) Enter answer in root form Enter answer in decimal form (for continuous marking purposes only-not graded) 4.2 Determine ACB, given that ACB is obtuse. 4.3 If the angle of depression from the top of the lighthouse D to A is B = ", determine the distance between buoy A and the tower.
