Wonder why a "teacher?" would provide such a misleading diagram...

The problem is easy if the angles at A and C are right angles. However, equal angles are not normally marked with a dot unless their value isn't being given. The problem is much more interesting if one doesn't assume that they are right angles. It seems that it's still the case that the value of x can be shown to be 2√6, but the angles at A and C needn't be right angles. For example, the diagram can be as shown below. Triangles.PNG
