Find the Angle $\theta$ (In Radians and Degrees)between the Lines $\begin{array} { l } 12 x + 6 y = 18 \\3 x - 2 y = - 1\end{array}$

Find the angle $\theta$ (in radians and degrees) between the lines.Round your answer to four decimal places for radians and round your answer to one decimal places for degree. $\begin{array} { l } 12 x + 6 y = 18 \\3 x - 2 y = - 1\end{array}$ ​

A) ​ $\Theta \approx 1.1071 \text { radians } \approx 64.4 ^ { \circ }$
B) $\theta \approx 1.1071 \text { radians } \approx 62.4 ^ { \circ }$
C) $\theta \approx 1.1071 \text { radians } \approx 65.4 ^ { \circ }$
D) $\theta \approx 1.1071 \text { radians } \approx 63.4 ^ { \circ }$
E) $\theta \approx 1.1071 \text { radians } \approx 61.4 ^ { \circ }$
