Answer:

x = 14°

Step-by-step explanation:

The triangle's interior angle at C is the supplement of the exterior angle marked 124°.

C = 180° -124° = 56°

The exterior angle at B is the sum of the remote interior angles:

6x = 56° +2x

4x = 56° . . . . . . subtract 2x

x = 14° . . . . . . . . divide by 4
