Answer:

<h2><u>x = 8.2</u></h2>

Step-by-step explanation:

A^2+B^2=C^2 is the pythagorean theorem to find a missing siede of a triangle.

First triangle on the right:

5^2+B^2=10^2

25+B^2=100

B^2=75

B=8.66025404

B=8.7

Second triangle of left:

3^2+B^2=8.7^2

9+B^2=75.69

B^2=66.69

B= 8.16639455

B=8.2

x=8.2
