Last tutor was absolutely useless, he told told me I'm wrong, please help me with this, take a look at the gyazo for clarification.

In your writing, please explain what is this: m∠C-AB-D = 30.

Usually, an angle is denoted by one letter (symbol) or by three letters (symbols).

This term m∠C-AB-D is unusual and requires additional explanations.
Would you please provide them?

I think that the previous tutor pointed you the same thing.
