Question

A supporting wire is to be attached to the top of a 43-foot antenna. If the wire must be anchored 43 feet from the base of the antenna, what length of wire is required? 

Answer 1

You have a right triangle where the legs are each 43 feet and the hypotenuse is the length of the wire.

a²+b²=c²

43²+43²=c²

1849+1849=c²

3698=c²

√3698=√(c)²

60.81118=c

c≈60.81118 feet
