Question

A pole is used to support an observation platform. The top of the pole is secured by two guy wires, one 18 and the other 21 feet in length. The 18 foot guy wire makes a 65± angle with the ground. How far apart, to the nearest foot, are the two wires at the points where they are anchored to the ground?

Answer 1

Let $A$ be the point on the ground to with the 18 foot guy is anchored and $D$ the point on the ground to with the 21 foot guy is anchored.

We can conclude that the the two wires at the points where they are anchored are 21 feet apart. Check the procedures in the picture attached.
