**MathMate**, Monday, March 29, 2010 at 10:52pmDraw a diagram, and it will be clear that the pole is opposite to the angle the wire makes with the ground.

Since the wire is at an angle, it is also the hypotenuse of the right triangle.

The ratio

sin(θ)=opposite/hypotenuse

=65/80

is what you need to find the angle using θ=sin^{-1}(65/80).

Post your answer for a check if you wish.
