Answer:
D
Step-by-step explanation:
As the angle Known to us is (2y-3)°
Now
∠B = (2y-3)° (when two parralel lines are cut by another line then angles opposite are equal)
∠D=180-(2y-3)° (Because angle to the line is same as B and as on one line total angle is 180° one part equals to B so other equals to 180-∠B)
Similarly
∠Q=∠D = 180-(2y-3)°
Because interior angles of a line cutting by a same line will be equal
