Can u help me plz and thank u ​
Elan Coil [88]

Answer:

Step-by-step explanation:

∠CBA + ∠ABD  = 180   {linear pair}

2x - 6 + x +1 = 180

3x -5 = 180

3x = 180 +5

3x = 185

x = 185/3

x = 61 2/3

2x-6=2*61\frac{2}{3}-6\\\\=2*\frac{185}{3}-6\\\\=\frac{370}{3}-\frac{18}{3}\\\\=\frac{352}{3}=117\frac{1}{3}
