Answer:
6√2
Explanation:
This is a right triangle. The legs of a right triangle are the sides that make up the right angle, and the hypotenuse is the side opposite to the right angle. To find x, we will use the Pythagorean Theorem. This states that a² + b² = c², where a and b are the legs and c is the hypotenuse. Since we know that the legs are both x and the hypotenuse is 12, we can plug these values into our equation to get x² + x² = 12².
2x²=144 → x² = 72 → x = √72, which simplifies to x = 6√2. Hope this made sense and helps!
