Question

you are installing a support wire for an electrical pole. the pole is 25 feet and the ground connection is 10 feet from the base of the pole. the wire is sold per whole feet. how many feet of support why should you purchase

Answer 1

ans=26.92

use trigonometric ratios

a²= b²+c²

a²=25²+10²

a²=625+100

now take square root on both sides

a

`\sqrt{a { }^(2) } = √(725)`

a=26.92

a=27 (2decimal place)
