Question Analysis
This problem assesses the understanding of the side ratios in a 30-60-90 triangle.

Key Concept Explanation
In a 30-60-90 triangle, the hypotenuse is twice the length of the shorter leg, and the longer leg is times the length of the shorter leg.

Step-by-step Solution
1. Identify the given hypotenuse: 20 units
2. Use the ratio: Hypotenuse = 2 * Shorter Leg → Shorter Leg = units
3. Use the ratio: Longer Leg =
