Find the value of x

A. 5 square root 2/2
B 5
C 10
D 10 square root 2

The answer is C

Step-by-step explanation:

That side with the 5 is equal to 7.071067812 (irrational number)

To get x you need to use the equation a^2 + b^2 = c^2

A^2 and B^2 will both be the same thing. The red line indicates they are the exact same length.

7.071037812 ^2 is 50

Now your equation would be 50+50= c^2 (which is the same as x^2)

100= c^2 is simplified by finding the square root of 100.

Your answer is 10 for side X because the square root of 100 is 10.

This problem was solved using the Pythagorean Theorem.
