Side a of the triangle is a utility pole. Henry would like to know how long the guy wire, c, should be.
1 answer:
We know that the pole is perpendicular to the ground
And that the length of the pole is 20 feet tall, and the base is 15 feet
Now, the guy wire is a wire that provides support to the pole by connecting the top of the pole to the ground
So this represents a right angled triangle (refer image), and the hypotenuse is the length of the guy wire
Using Pythagoras theorem, we can find out the length of the hypotenuse
⇒ Hypotenuse² = Perpendicular² + Base²
⇒ Hypotenuse² = 20² + 15²
⇒ Hypotenuse² = 400+225
⇒ Hypotenuse² = 625
⇒ Hypotenuse = √625
⇒ Hypotenuse = 25
Hence, the correct option is B 25 ft.

Answer:
5
Step-by-step explanation:
There are 2 ways to look at this. I will explain both.
First we have the 3-4-5 triangle method, stating that any triangle with sides 3 and 4 will have the last side as 5.
Now, for the more complex way of doing this, we can use the Pythagorean theorem to solve this problem.
Pythagorean theorem:
We can use 4 for a and 3 for b
You will now have
Then take √25, or 5.
