7th Grade Math The Pythagorean Theorem

[JAshford]

Im soory to post this problem...but I am really having a problem with it.I was hoping you all could help me understand it.

it states: A utility pole 10 m high is supported by two guy wires. Each guy wire is anchored 3 m from the base of the pole. How many meters of wire are needed for the guy wires? ( round to the nearest tenth)
My answer: 1,000 meters of wire are needed for the guy wires.
Is this correct?

I multiplied 10 to the3rd power....

Im soory to post this problem … (I'm wondering why are you experiencing the emotion of "soorow".) :?

… My answer: 1,000 meters of wire are needed for the guy wires. Is this correct? … Common sense tells us that 1,000 meters is not even close!

If you stuck your head out of your bedroom window that's 10 feet above the ground, and you're talking to somebody on the ground who is standing 3 feet from your house, you wouldn't think that this person is well over one football field away from your face, would you?

… I multiplied 10 to the 3rd power 10^3 has nothing to do with this exercise. You need to use the Pythagorean Theorem, instead.

Did you draw a picture?

The two guy wires are each the hypotenuse of identical right triangles. The legs on each of these two right triangles are 3 and 10.

Have you ever used the Pythagorean Theorem? Do you know what it means?

Please show whatever work that you can, or explain what you're thinking, if you would like more help with this exercise.
