Answer:

10

Step-by-step explanation:

Let x represent the third side

This is a right triangle

In right triangle the sum of square value of both legs is equal to square value of hypotenuse(the third side in this case)

Let x represent the third side

5^2 + 5[tex]\sqrt{3}[/tex]^2 = x^2

25 + 75 = x^2

100 = x^2 find the root for both sides

10 = x
