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
