### Vector Math: Resultant Moment Calculation

**Problem Statement:**
Two 75-lb forces act on the frame as shown. Determine the resultant moment produced by the two forces.

**Diagram Description:**
The diagram consists of a rigid frame with various dimensions and applied forces. The frame is composed of horizontal and vertical segments, and the key dimensions and force applications are labeled as follows:

- Point A: The fixed base of the frame.
- Point B: The intersection point of the vertical and horizontal segments, located 3 ft above Point A.
- The entire height from Point A to the top is 9 ft.

Dimensions:
- Distance from Point A to Point B vertically: 3 ft.
- Horizontal distance from Point B to the right: 2 ft.
- Another horizontal distance from Point A vertically to the midpoint of a diagonal segment: 3 ft.
- Horizontal and vertical lengths of the diagonal segment: 3 ft.

Applied Forces:
- First 75-lb force at Point B acting to the right, with a downward angle with a ratio of 3 (horizontal) to 4 (vertical).
- Second 75-lb force applied 3 ft to the left and upwards at an angle to a diagonal segment with a ratio of 3 (horizontal) to 5 (vertical) with 4 vertically.
  
**Options for the Resultant Moment:**
- 255 lb-ft
- 15 lb-ft
- 90 lb-ft
- 270 lb-ft
- 510 lb-ft

**Instructions:**
Evaluate the given options and calculate the resultant moment produced by the two given forces acting on the frame.

**Calculation Note:**
To solve for the resultant moment, apply the concept of moments (torque), which is calculated as the force multiplied by the perpendicular distance from the point of rotation (in this case, Point A). Use the given geometrical dimensions and force magnitudes to find the contribution of each force to the moment about Point A.
