Question 389505: In my pre ap geometry class, we have been working with tan, sin, and cos to find angles and lengths using the math solver on the calculator. I am having difficulty with this problem(there is a 90 degree angle):
A ski slope has a 42 degree incline and is 170 yards long. Find the vertical drop(height) of the slope.
Answer by josmiceli(19441) (Show Source): You can put this solution on YOUR website!
You have to imagine that you are starting at the bottom of the slope
and walking uphill with a tape measure. When the tape measure
reads 170 yds, you stop. Now you want to know how high vertically
you are from ground level where you started.
You knew before you started that the slope was 42 degrees.
I'll call the height I want to know
I can say
Multiply both sides by

gives me the vertical height in yards where the tape measure reads 170 yds
I get about yds
