in this diagram below de is parallel to xy.what is the value of y

Answer:
B. 75°
Step-by-step explanation:
When lines that are parallel are crossed by a transversal , angles in matching corners are equal and called corresponding angles
To get the value of the angle;
180°-105°= 75°.................sum of angles on a straight line
This angle corresponds to angle y because of the parallel lines DE and XY
