This is using your trig function.

sine = opposite/hypotenuse

In this problem, we are finding the hypotenuse. Think of the mountain as a right triangle.

sin(25.2) = 1808/x and you are solving for x.

No - you should have done 1808/.4257 and get 4246.33.

We use sine = opp/hyp

Let x be the height of the slope that we are seeking.

sin(25.2 degrees) = 1808 feet/x

Multiply both sides by x and we get:

sin(25.2 degrees)(x) = 1808 feet

Next: Divide both sides by sin(25.2 degrees) to find x.

x = 1808 feet/sin(25.2 degrees)

x = ????

Can you finish?
