Answer:

The answer to your question is z = [tex]\sqrt{24}[/tex]

Step-by-step explanation:

Process

I'll solve this problem using proportions, I hope it helps you

We consider the adjacent side of both triangle

Adjacent side small triangle = x    Adjacent side big triangle = 10

Proportion of these sides = [tex]\frac{x}{10}[/tex]

Now, consider the opposite side of both triangles

Opposite side fo small triangle = 2  Opposite side big triangle = x

Proportion = [tex]\frac{2}{x}[/tex]

Now, equal both proportions and solve for x

                           [tex]\frac{x}{10} = \frac{2}{x}[/tex]

                                           x² = 20

                                           x  = [tex]\sqrt{20}[/tex]

                                          x = 2[tex]\sqrt{5}[/tex]        

Using Geometric mean

x = [tex]\sqrt{2x10} = \sqrt{20}[/tex]

Using the Pythagorean theorem to find z    

z² = (√20)² + 2²

z² = 20 + 4

z² = 24

z = [tex]\sqrt{24}[/tex]
