A helicopter leaves its base and flies 40km on a bearing of 050° and then 30km on a 3 bearing of 105° a) Draw a scale diagram to show this information. How far is the helicopter from its base? b) On what bearing does the helicopter need to fly in order to return to its base?

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.
