Question

What is the length for the 3rd side? write in simplest radical form if needed

Answer 1

10

Explanation:

Using Pythagoras' identity in the right triangle.

Let the third side be x , then

x² + 6² = (2
`√(34)` )²

x² + 36 = 136 ( subtract 36 from both sides )

x² = 100 ( take the square root of both sides )

x =
`√(100)` = 10
