If the angles of a quadrilateral are in the ratio 3:5:9:13, then find the measure of smallest angle.

Explanation

To find the measure of the smallest angle in a quadrilateral where the angles are in the ratio 3:5:9:13, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Ratio**: The angles of the quadrilateral are given in the ratio 3:5:9:13. This means we can express the angles in terms of a variable \( x \). Let:
- Angle 1 = \( 3x \)
- Angle 2 = \( 5x \)
- Angle 3 = \( 9x \)
