Can anyone help me out in finding the value of x in the following figure??
While drawing i missed out a value. $\angle DCA = 20^{\circ}$. Not sure how to go about this.

The angle in the middle point can't be $50^{\circ}$ – MattG88 Nov 16 '16 at 05:01

Look up "adventitious angles". See also http://math.stackexchange.com/questions/548292/determinating-the-angle-in-a-triangle – Gerry Myerson Nov 16 '16 at 05:04

@MatG88 Why do you think this? – Momo Nov 16 '16 at 05:06

@Momo Because it is an obtuse angle – MattG88 Nov 16 '16 at 05:09
