Question 2 a) In a right angled triangle PQR, angle P =90°, sin Q =(13/19). Find all sides and all angles. (3) b) A ladder must reach the top of the building. the base of the ladder will be 2.3m from the base of the building. The angle of elevation from the base of the ladder to the top of the building is 35°. Find the height of the building and the length of the ladder. (7) c) Find the period, amplitude and phase of the following periodic functions and plot a graph of i) and ii). i) y = sin(2t) ii) y = 4 sin(3t) (10) iii) y = 6 cos (²) iv) y = 3sin(2t +30°)
