Answer:
C.d=125
Step-by-step explanation:
We are given that two parallel lines r and s intersect by a transversal line q.
We have to find the value of d.
Vertical angles: When two lines intersect then the pair of opposite angles formed by intersecting lines are called vertical angles.
Vertical angles theorem:It states that vertical angles that are opposite to each other formed by two intersecting lines are congruent.
d and 125 degrees are vertical angles because these angle formed by two intersecting lines q and s and opposite to each other.
Therefore, by vertical angles theorem
[tex]d=125^{\circ}[/tex]
Hence, the value of [tex]d=125^{\circ}[/tex].
Option C is true.
