I need help finding x
BigorU [14]

Answer:

The answer to your question is      x = \sqrt{50}    or x = 5\sqrt{2}

Step-by-step explanation:

To solve this problem use the Pythagorean theorem because two right triangles are formed.

                    c² = a² + b²

c = 10

a = x

b = x     Because in a square all the sides measure the same.

                    10² = x² + x²

- Simplify

                    100 = 2x²

                    x² = 100/2

                   x² = 50

                    x = \sqrt{50}    or x = 5\sqrt{2}
