Answer should be 14.66 degress and 0.484 gamma R^2 x W Please explain

### Problem Description

If the gate is half filled by water (depth = R/2 as shown in the figure), determine the magnitude and direction of the resultant force.

### Diagram Explanation

- The diagram illustrates a quadrant-shaped gate submerged in water.
- The quadrant is part of a circle with radius \( R \).
- The water fills half the gate, thus the water depth is \( R/2 \).
- Points in the diagram:
  - \( A \): Top left corner of the gate.
  - \( B \): Bottom right corner of the gate, adjacent to the boundary.
  - \( C \): Top right corner where the gate is hinged.
- The curved edge \( AB \) of the quadrant is submerged in water.
- The hinge is located at corner \( C \).
  
### Additional Considerations

- The water exerts hydrostatic pressure on the gate.
- The problem asks to find both the magnitude and the direction of the resultant force applied by the water on the gate.
