Answer:

x = 14

Step-by-step explanation:

∠ DCA and ∠ BCF are adjacent angles and sum to 180° , then

∠ DCA = 180° - 124° = 56°

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

6x is an exterior angle , then

6x = 2x + 56 ( subtract 2x from both sides )

4x = 56 ( divide both sides by 4 )

x = 14
