Find the Angle $\theta$ (In Radians and Degrees) Between the Lines $\begin{array} { l } x - 2 y = 9 \\10 x + 2 y = 7\end{array}$

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. $\begin{array} { l } x - 2 y = 9 \\10 x + 2 y = 7\end{array}$

A) $\Theta \approx 1.3045 \text { radians } \approx 75.7 ^ { \circ }$
B) $\Theta \approx 1.3045 \text { radians } \approx 74.7 ^ { \circ }$
C) $\Theta \approx 1.3045 \text { radians } \approx 73.7 ^ { \circ }$
D) $\theta \approx 1.3045 \text { radians } \approx 76.7 ^ { \circ }$
E) $\Theta \approx 1.3045 \text { radians } \approx 72.7 ^ { \circ }$
