Answer:
The correct option is 3.
Step-by-step explanation:
Given information: Lines r and s are parallel to each other.
If two lines intersect each other at a point then the opposite angles are called vertically opposite angles and these vertically opposite angles are always same.
From the given figure it is clear that the angle having measure d° and angle having measure 125° are vertically opposite angles. So,
[tex]d^{\circ}=125^{\circ}[/tex] (Vertically opposite angles)
[tex]d=125^{\circ}[/tex]
The value of d is 125, therefore the correct option is 3.
