Find the length of the hypotenuse !!

bearhunter [10]

Answer:

Step-by-step explanation:

To find the hypotenuse, you would use the Pythagorean theorem.

$A^{2} +B^{2} =C^{2}$

We can plug 8 and 15 into A and B\

$8^{2} +15^{2} =C^{2}$

We can simplify this to

64+225= $C^{2}$

289 = $C^{2}$

To get C by itself not squared, we can do the square root of both sides.

$\sqrt{289} =\sqrt{C^{2} }$

If we simplify, we get

17 = C or C = 17

Therefore the length of the hypotenuse is 17.
