Question

A plane flies from A and B,a distance of.a 120km on a bearing of 035°. If then changes direction and flies to C,a further distance of 200km on a bearing of 125°. Find:          1. The distance AC to nearest kin.                    2. The bearing of C from A

Note that the course change was 90°. So, #1. AC^2 = 120^2 + 200^2 #2. The bearing from A to C is θ+35° where tanθ = 200/120
