### Problem Statement

As shown, an L-shaped bar is supported by a pin at joint A. The bar's dimensions are \(a = 620 \, \text{mm}\) and \(b = 400 \, \text{mm}\), and the bar is subjected to a force with magnitude \(F = 5.35 \, \text{kN}\) at joint B. Ignoring the bar’s weight, find the actual orientation of the applied force. What is the value of the angle \(\theta\)?

Express your answer in degrees to three significant figures.
 
### Diagram Description

The diagram illustrates an L-shaped bar supported by a pin at joint A. The bar extends horizontally to the right from joint A for a length \(a = 620 \, \text{mm}\), then turns upwards vertically for a length \(b = 400 \, \text{mm}\). A force \(F\) is applied at the top end of the vertical section at joint B, at an angle \(\theta\) to the vertical.

#### Dimensions:
- Horizontal length \(a = 620 \, \text{mm}\)
- Vertical length \(b = 400 \, \text{mm}\)
- Force magnitude \(F = 5.35 \, \text{kN}\)

### Answer Submission

Below the diagram, there is a box where students are expected to input their answer for the angle \(\theta\) in degrees to three significant figures.

θ = ______ degrees
