Question

In a right triangle the length of a hypotenuse is c and the length of one leg is a, and the length of the other leg is b, what is the value of b, if b c=9, a=7?

Answer 1

Answer

square root of 32

Step-by-step explanation:

in a right triangle we can use Pythagorean theorem to find B

$C^{2} =A^{2}+B^{2} \\\\ 9^{2}=7^{2}+B^{2} \\81=49+B^{2} \\81-49=B^{2} 32=B^{2}\\ B=\sqrt{32}$we substitute C for 9 and A for 7
