If you have a right triangle with one leg side 8 in, the hypotenuse is 12 in,

and the other leg is unknown, y.

What is the equation you would use to find the length of side y ?

O 82+12² = y²
O 82 + y² = 122
○ (8+12)² = y²
○ (8+ y)² = 122

The equation you would use to find the length of side y is:

8² + y² = 12²
