A Flagpole Is To Be Made Firm. How Much Wire Will Be Needed If, From 3 Pegs, Each 120 Cm Away From T

A flagpole is to be made firm. How much wire will be needed if, from 3 pegs, each 120 cm away from the foot of the pole, wire will be tied to a point on the pole 2 1/2m from the ground?

 

using Pythagorean Theorem:

x = \sqrt{120^{2} +2.5^{2} }

x = 120.026

length of wire needed for 3 pegs = 3x

length of wire needed for 3 pegs = 3 × 120.026

length of wire needed for 3 pegs = 360.0781

answer: 360.0781
