###### Question details

This is a Year 9 Pythagoras Theorem question, student had not learned Trigonometry yet.

In an army navigation exercise, a group of soldiers hiked due south from base camp for 2.5km to a water hole. From there, they turned 45 degree to the left, to head south-east for 1.6km to a resting point. When the soldiers were at the resting point, how far (correct to one decimal place):

a) east were they from the water hole?

b) south were they from the water hole?

(I solved these 2 parts, but can't understand what part c is asking for)

c) were they in a straight line from the base camp? Please use a diagram to explain.
