0 20 40 60 80 100 120 140 160 180
y 7.0 4.2 -0.9

(b) Using a scale of 2cm to 20° on the x-axis and 2cm to 2 units on the y-axis, draw the graph of \(y = 3\mathrm{Sin}x + 7\mathrm{Cos}x\) for 0°

(c) Using the graph, find the;

(i) value of y when x= 150°,

(i) range of values of x for which y > 0.
