Answer:

I can't exactly remember how to either but I do know that they hypotenuse is 7 so z cannot be bigger than 7

Answer:

z = [tex]\sqrt{35}[/tex]

Explanation:

The triangles are similar so the ratios of corresponding sides are equal, that is

[tex]\frac{z}{5}[/tex] = [tex]\frac{7}{z}[/tex] ( cross- multiply )

z² = 35 ( take the square root of both sides )

z = [tex]\sqrt{35}[/tex]
