**Problem Statement:**

Find the angle \( \theta \) between the lines:

1. \( 2x + 3y = 6 \)
2. \( x - y = 5 \)

**Instructions:**

To find the angle between two lines, you can use the formula involving their slopes:

\[
\tan \theta = \left| \frac{m_1 - m_2}{1 + m_1 \cdot m_2} \right|
\]

where \( m_1 \) and \( m_2 \) are the slopes of the two lines. First, convert each line to the slope-intercept form, \( y = mx + b \), to identify the slopes. Then, apply the formula to find \( \theta \).
