please this question is wrong. the answer is 130 degrees
you do sum of angles in a polygon = (n-2)x 180 = 540 since it is a pentagon of 5 sides.
then you add all the interior angles and subtract from 540 which is
540-310 =230
but θ + x = 360 (angle at a point)
so θ = 360 -230 = 130 which is D not E
