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

Multiple Choice

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) $\Theta \approx 1.3045 \text { radians } \approx 72.7 ^ { \circ }$
