To solve for the angle, let’s say the value is W.
We have the sides opposite and adjacent to the angle, so we can use the trigonometric function tangent to solve.
The tangent of an angle is the side opposite divided by the side adjacent so:
tan(W) = 11200ft/34452.2ft
But we are solving for the angle. In order to do this, take the inverse tangent of both sides. This will give us:
W= tan^-1(11200ft/34452.2ft)
Plug this into your calculator to get
W= 18.00872665 degrees
