I need to know the missing side.

x = 13

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² = 5² + 12² = 25 + 144 = 169 ( take the square root of both sides )

x = = 13

means if you're already damaged some way when you take out a medical insurance you will not get full compensation for that injury that you already have.
