Question

Lars rides a chairlift to the top of a mountain. The chairlift rises at a constant angle of 37°. If the length of the chairlift ride is 1,392 m, what is the elevation gain from the base of the chairlift to the top?

Answer 1

Let's draw this out

Answer 2

Do you know which trig function we have to use to calculate x, which is the length from the base to the top?

Answer 3

The function should be sine and instead of 'x'. you try to use 'y'.

Answer 4

The variable we use is irrelevant (:

We can use 'x' or we can use 'q' or even 'h'
We just have to define it and stay consistent throughout the problem :)
