Verified Answer :

the answer would be letter c because you have to use orders of operations io on aka A^2+B^2=C^2
how to set it up woulf look like this: a^2= 7^2
B^2=?, and C^2=13^2
in other words a=7squared
B=?
and C=13 squared
so the problem would end up like this:.77+B2=1313
49+B2=169
so now you subtract 169 from 49 and that equals B*2=√120

calculista

we know that

in the right triangle of the figure

Applying the Pythagorean Theorem

\(13^{2} =b^{2} +7^{2} \\ b^{2} =13^{2}-7^{2}\\ b^{2}=120\\ b=\sqrt{120} \ cm\)

therefore

the answer is the option

C) \(b=\sqrt{120} \ centimeters\)
