I have a doubt regarding the official explanation given for this problem. You can see both the question and the explanation in the picture.

The whole explanation as you can see rests upon the fact that angle DAB measures x degrees.

My question is - How have they assumed that angle DAB = x degrees?

Thanks a lot for being so helpful Mitch.

For anyone else who is wondering what Mitch and I are talking about - This is a problem from the Official guide Quantitative review, 2nd edition
