Question

A 50 foot cable is stretched from the top of an antenna to an anchor point on the ground 15 feet from the base of the antenna. How tall is the antenna?

Answer 1

the cable is stretched from the top of the antennae, and there is STILL 15 feet left.

so,

50 + 15 = the total length of the antennae
50 + 15 = 65

So, the total length of the antennae is 65 feet
