I think I have an idea how but I'm not completely sure. I had this question on some work at school and drew it out online.

i dont think so, that info wasn't given on the paper. The only angle that was given was DEC bein 30 degrees.

Let EA=x-2, EC=x

#

Then you can use ||A = 1/2 ab sin C|| on the triangle

#

reduces down to a quadratic equation
