so it’s A
in all the other ones we can see that the angles in the same position as x and 75 are all equal
and because the question tells us that they are all structured the same with p and f being parallel we can assume x is equal to what’s congruent to it
there is a rule that states this
cap congruent angle postulate i believe
which states that if two parallel lines are cut by a transversal, then corresponding angles are congruent
