Question

Find the length of the third side. if necessary, write in simplest radical form.

Answer 1

10

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
`√(3)`^2 = x^2

25 + 75 = x^2

100 = x^2 find the root for both sides

10 = x
