Find the Angle $\theta$ (In Radians and Degrees)between the Lines $\begin{array} { l } 6 x - 8 y = 8 \\6 x + 8 y = 7\end{array}$

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.​ $\begin{array} { l } 6 x - 8 y = 8 \\6 x + 8 y = 7\end{array}$ ​

A) ​ $\Theta \approx 1.3221 \text { radians } \approx 76.7 ^ { \circ }$
B) $\theta \approx 1.3221 \text { radians } \approx 74.7 ^ { \circ }$
C) $\Theta \approx 1.3221 \text { radians } \approx 75.7 ^ { \circ }$
D) $\Theta \approx 1.3221 \text { radians } \approx 77.7 ^ { \circ }$
E) $\theta \approx 1.3221 \text { radians } \approx 73.7 ^ { \circ }$
