The ones which are discrete would have answers like 1234 and would not have any decimal answers so you can’t have half a student or half a chair there for those of the two that are discrete
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.
