For this, we will be using the quadratic formula, which is
, with a=x^2 coefficient, b=x coefficient, and c = constant. Our equation will look like this: 
Firstly, solve the multiplications and the exponents: 
Next, do the addition: 
Next, your equation will be split into two:
. Solve them separately, and your answer will be
The answer is:
11.18
Hope This Helps!!

You can use trigonometry and the tangent to get:
tan(11°)=150/x
so x=772 ft
I think 0 because 9+11+12=32
32+-32 or 32-32= 0
