dbc is a triangle, with
The angles are complementary.
Angle DBC = 90 - Angle CDB = 90 - 38 = 52°

Rectangles have 90 deg corners so take 90 - 38 = 52 deg

As per ques DBC forms a triangle, and since ABCD is a rectangle angle DCB=90 deg.
Therefore angle CDB+DBC=90 deg.
Since we know angle CDB=38, angle DBC=90-38=52 degrees(Ans)

an.CDB=an.DBA(alternate interior an.)
an.DBA+an.DBC=90deg.(an. of rectangle 90 deg.)
therefore an.DBA=90-38=52deg.
