Question

A wire is attached to the top of a 15 foot flagpole the other end of the wire is attached to a point on the ground that is 18 feet from the bottom of a flagpole how long is the wire

Answer 1

23.4 ft

Explanation:

The straight-line distance (d) from the top of the pole to the attach point on the ground is given by the Pythagorean theorem:

d² = 15² +18² = 549

d = √549 = 3√61 ≈ 23.4 . . . . feet

The wire is about 23.4 feet long.
