    we have two right angle triangles. use trigonometric ratios sin(angle) = perpendicular/hypotenuse for both triangles. one will give you the height from ground to point A, the other will give ground to point be. subtract to find the length of the pole.

    @azka.niazi why are you using sine?

    OOps! that's a tangent! sorry! that should be tan(angle) = perpendicular/base (thanks for pointing out @zarkon)
