Lamont works for an electric utility and is installing a 40 foot utility pole as shown. lamont drills the anchor of a support cable into the ground 15 feet from the base of the pole. what is the minimum length of cable lamont needs?

Approximately 43 feet of minimum cable is needed.

Step-by-step explanation:

This problem can be solved using Trigonometry and Pythagorean theorem. Pythagorean theorem applies on right-triangles (which are known to have one 90° angle). The theorem states that the square of the Hypotenuse is obtained by the squared sum of the other two sides of the triangle (i.e the two sides forming the 90° angle - with the hypotenuse side being across it as:

          Eqn. (1)

where

is the hypotenuse

is a side

is a side

Now in this case, the utility pole must be perpendicular to the ground and the anchor being parallel to the ground, and a 90° angle formed between them. Conclusively the cable length will be represented by the hypotenuse in a right triangle. So here we have and . Plugging in Eqn.(1) and solving for we have:

So we conclude that the minimum length of cable needed by Lamont is

≈43 feet (rounded up).

the answer is b; false. 2 dimensional things are a lot more different from 3 dimensional things.
