Question

The top of 12 ft high pole is tied to a nail in the ground that is 3.5ft away from the base of the pole. Find the length of the wire used.

Answer 1

Answer:

12.5 ft.

Step-by-step explanation:

The pole and the wire make right triangle with the ground.

By Pythagoras theorem,

12^2+3.5^2=length of wire^2

therefore, length of wire = √12^2+3.5^2

= √156.25

= 12.5 ft.
