Lets just solve all the angles:

  B =  180 - ( I + J)

I = 56 degrees, J is 90 degrees  because D is 90; because angles on straight line add up to 180 degrees.

so B is 180 - ( 56+90), which equals 34 degrees.

Angle C = 180 - (B +A); angles in a triangle add up to 180 degrees.

B = 34, A = 38,

so C is 180 - (34+38)

= 108 degrees.

Angle F = 360 - (E + D + C); angles in a quadrilateral add up to 360 degrees.

E = 90, D = 90, and C = 108.

So F = 360 - ( 90 + 90 + 108), which equals 72 degrees.

Hope  this helps!  If you are not satisfied you can as any question.
