Question

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

Answer 1

6

Explanation:

The value of the square length of the hypotenuse is equal to sum of the square length of the two legs: let x represent the missing side

`\sqrt{} 85^(2)` = 7^2 + x^2 calculate the powers

85 = 49 + x^2 subtract 49 from both sides

36 = x^2 find the root of the both sides

6 = x
