ray EC bisects angle BED, The measure of angle AEB equals 11x minus 12.and The measure of angle CED equals 4x plus 1.. Find measure of angle AEC.

1. Can't tell whether A is in between B and E or not.

But, you know that BEC=BED

If A is between B and C

BEA+AEC=BEC
11x-12 + AEC = 4x+1
AEC = 13-7x

or, if B is between A and C,

AEC-AEB=BEC
AEC-11x+12 = 4x+1
AEC = 15x-13

Of course, A could be a lot of other places, too.
