Find the length of side x in simplest radical form with a rational denominator.

x =

Step-by-step explanation:

the 2 legs are congruent

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 , then

x² = ( )² + ( )² = 11 + 11 = 22 ( take square root of both sides )

x =

The Pythagoras theorem states that the sum of squares of two sides of a triangle equals the square of the longest side , i.e. the hypotenuse.

step-by-step explanation:

subtract 7, so the answer is x < = 3, or c.
