The slopes of two lines are `(1)/(2)` and `3`. Find the angle between them.

Explanation

To find the angle between two lines with slopes \( m_1 = \frac{1}{2} \) and \( m_2 = 3 \), we can use the formula for the tangent of the angle \( \theta \) between two lines:

\[ \tan \theta = \frac{m_2 - m_1}{1 + m_1 m_2} \]
