**Title: Solving Reactions at C and D Using the Force Triangle Method and Law of Sines**

In this exercise, we aim to find the reactions at points C and D by utilizing the force triangle method and the law of sines. The setup includes a structure with a 200 lb force applied vertically downward at point A.

**Diagram Details:**

- **Structure Configuration:**
  - A horizontal beam is shown with point A on the left where the force is applied.
  - The beam is supported by two connections, C and D, which are at the bottom right.
  - Points B and D each create a 3-foot horizontal span from the left to right.
  - Vertical distances indicate 2 feet from point D to the inclined support and an additional 2 feet from the line of action passing through point C to the inclined surface.

- **Force:**
  - A red arrow at point A indicates a downward force of 200 lb.

Given these parameters, apply the force triangle method and the law of sines to calculate the unknown reactions at supports C and D. Understanding these reactions helps in analyzing the equilibrium and stability of the structure under the given load condition.
