Answer:
x = 66
Step-by-step explanation:
[tex]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}}[/tex]
