Explanation

In a 30-60-90 triangle, the side opposite the 30 degree angle is half the length of the hypotenuse. Since the hypotenuse is 10, the side is 10 / 2 = 5.

AI explanation

In a right triangle, the side opposite the 30 degree angle is always half the length of the hypotenuse. Since the hypotenuse is given as 10 units, the opposite side is 10 divided by 2. This makes the length 5 units.
