Question

How long is the wire stretching from the top of a 22 foot telephone pole to the ground 8 feet from the pole?

Answer 1

x is the hypotenuse.

Let c = hypotenuse

To solve this, you'll need to follow the a² + b² = c² formula.

Let a and b = other sides

Plug into corresponding variables.

(22)² + (8)² = c²

Simplify

484 + 64 = c²

c² = 548

Isolate the c. root both sides

√c² = √548

c = √548

c = 2√137, or 23.409

x = 23.409 

hope this helps

Answer 2

Answer: 23.4

Step-by-step explanation:

c = hypotenuse or x

22^2 + 8^2 = c^2

c^2 = 548

$\sqrt{ c^{2} } = \sqrt{548}$

c = 23.409 rounded to the tenths is 23.4
