Question

5. A ski slope is 310 yards long with a vertical drop of 220 yards. Find the

angle of elevation of the ski run. Round to the nearest degree.

Answer 1

It helps to draw a picture so you can see which trig ratios to use but...

310 is the hypotenuse of the ski slope and the side length across from the angle you’re looking for is 220, the vertical drop.

You can use sin to find theta.

sinx= 220/310

sinx=0.70967...
x = sin inverse of 0.70967....
x = 45°
