To find the coordinates of the center of mass of the system, we use the following formulas for the center of mass in the x- and y-directions:

\[
x_{cm} = \frac{\sum m_i x_i}{\sum m_i}
\]
\[
y_{cm} = \frac{\sum m_i y_i}{\sum m_i}
\]

Where \( m_i \) are the masses and \( x_i \), \( y_i \) are their corresponding coordinates.

From the figure:
- \( m_1 = 3.3 \, \text{kg} \), at \( (x_1, y_1) = (1, 0) \)
- \( m_2 = 4.9 \, \text{kg} \), at \( (x_2, y_2) = (2, 1) \)
- \( m_3 = 6.4 \, \text{kg} \), at \( (x_3, y_3) = (0, 3) \)

### Step 1: Calculate \( x_{cm} \)
\[
x_{cm} = \frac{(3.3 \times 1) + (4.9 \times 2) + (6.4 \times 0)}{3.3 + 4.9 + 6.4} = \frac{3.3 + 9.8 + 0}{14.6} = \frac{13.1}{14.6} \approx 0.90 \, \text{m}
\]

### Step 2: Calculate \( y_{cm} \)
\[
y_{cm} = \frac{(3.3 \times 0) + (4.9 \times 1) + (6.4 \times 3)}{3.3 + 4.9 + 6.4} = \frac{0 + 4.9 + 19.2}{14.6} = \frac{24.1}{14.6} \approx 1.65 \, \text{m}
\]

Thus, the coordinates of the center of mass are:
- \( x_{cm} \approx 0.90 \, \text{m} \)
- \( y_{cm} \approx 1.65 \, \text{m} \)
