Find the value of z.7Xy3ZV[?]Z =Give your answer in simplest form.Enter

Answer 1

First, lets remember the property of right triangles as follows. Given a right triangle with the form:

The following formula is true:

$Z^2=m\times(m+n)$

So, in our case m=3 and m+n=7+3=10, if this we can find Z:

$Z^2=3\times(7+3)\rightarrow Z^2=30\rightarrow Z=\sqrt[]{30}$
