Question

Which equation could be used to find the length of the hypotenuse?

Answer 1

Hey!

The formula for finding the length of the hypotenuse is:

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

That means you have to square both numbers.

$6\ squared = 6^{2} \\ 11\ squared = 11^{2}$

That gives you:

$6^{2} + 11^{2} = c^{2}$

That means your answer is the first choice

$\framebox{Answer = 1st choice}$

Answer 2

$a {}^{2} + b {}^{2} = c {}^{2}$
$6 {}^{2} + 11 {}^{2} = c {}^{2}$
$36 + 121 = c {}^{2}$
$157 = c {}^{2}$
$\sqrt{157} = c$
$c = 12.53$
