Question

I really need some explanation cause like I’m confused

Answer 1

Answer:

85 ft

Step-by-step explanation:

Pythagorean Theorem:

$a^{2} + b^{2} = c^{2}$

Where a and b are sides and c is the hypotenuse.

Substitute:

$13^{2} + 84^{2} = c^{2}$

$169 + 7,056 = c^2$

$7,225 = c^2$

$\sqrt{7,225} = \sqrt{c^2}$

85 = c

85 feet
