Answer:
Incomplete question check attachment for diagram
Explanation:
Two parallel lines, cross by a transversal
The angle between one of the line and the transfer is 125° and this angle is opposite to angle d, so it is vertical opposite angle
Vertically Opposite Angles are the angles opposite each other when two lines cross, so it was the transversal line that cross the parallel lines
and we know that, vertical opposite angle is equal.
Then, d = 125°
