Using a scale of 2cm:45° on the horizontal axis and 2cm:1 unit on a vertical axis, draw the graphs of y=2 + sin x and y=3cosx on the same axes for
0°<\=×<\=360°.
a) Use your graph to solve the equations,
sinx +3=0
2 + sinx = 3cosx
b) State the maximum and minmum values of y=3 cosx

Answer this two poles, ab and ed, are fixed to the ground with the of ropes ac and ec, as shown: two right triangles abc and edc have a common vertex c. angle abc and edc are right angles. ab is labeled 13 feet, ac is labeled 15 feet, ec is labeled 10 feet, and ed is labeled 4 feet. what is the approximate distance, in feet, between the two poles? 11.14 feet16.65 feet14.35 feet15.59 feet
