Answer:
B
Step-by-step explanation:
both sides are equal to begin with so any x that you put in, will get multiplied by 7 and have 3 added to it
a) ∠PQR=65° (alternate interior angles theorem)
∠PRQ = 60° (linear pair)
x = 55° (angles in a triangle add to 180°)
b) ∠APQ and ∠PQR are congruent alternate interior angles.
