Answer:

x = 66

Step-by-step explanation:

m \angle \: 5 + m \angle \:6 = 180 \degree \\ (straight \: line \:  \angle  s) \\  \therefore \: (2x)\degree + 48\degree = 180 \degree \\ \therefore \: (2x)\degree  = 180 \degree -   48\degree\\   \therefore \: (2x)\degree  = 132 \degree   \\ \therefore \:x =  \frac{132}{2}  \\    \:  \:  \: \huge \purple{ \boxed{\therefore \:x =  66}}
