That's the wrong right triangle to draw.  Reading the problem carefully we want this one, figure attached.

So we have the usual 30/60/90 triangle but not to scale.  The sides come in ratio 1:√3:2=x:100:hypotenuse.  So

x = 100/√3 ≈ 57.735

We add that to our 133.2 for the total height of the Cyclone, 190.935.

Answer: 190.9

Start with the general formula. The key word is difference. So the general formula is 

D(x) = W(x) - R(x) Now substitute in the values for W(x) and R(x)
D(x) = 0.002x^3 - 0.01x^2 - (x^2 - 4x  + 13) Be very careful about the sign in front of the brackets.

D(x) = 0.002x^3 - 0.01x^2 - x^2 + 4x - 13 Do you see what that minus sign did? It affected all 3 terms.

D(x) = 0.002x^3 - 1.01x^2 + 4x - 13 <em>Note: -0.01 - 1x^2 = - 1.01 x^2</em>
That gives you a clear cut answer

C<<<<< answer.

That sign is the worst part of the question. Make sure you understand what it did.
