Question

A skier moves 100.0 m horizontally, and then travels another 35.0 m uphill at an angle of 35.0º above the horizontal. What is the skier's displacement from his starting point? (Use the graphical method to answer and include your scale on the graph paper.) Give both the magnitude and the angle in your answer.

Answer 1

Another right-angled triangle. First thing to do is work out the lengths of the two shorter sides

Answer 2

Then work out the hypotenuse of this new triangle, as well as the angle on the left hand side
