How do I express the angle of inclination as a function of d?

Question

A guy wire ( a type of support used for example, on radio antennas) is attached to the top of a 50 foot pole and stretched to a point that is d feet from the bottom of the pole.

Answer 1

Uh...This is more a math problem not personal finance...

Anyways...the angle = Θ = arctan(50'/d')

arctan is the inverse of the trig. function of tangent
