Question

in fig. AB||CD and Q is any point in between them such that angle BPQ = 20° and angle QRD= 30°,find angle PQR​

Answer 1

Answer:

angle PQR = 50°

Step-by-step explanation:

construction: draw a parallel line on angle PQR

so, it divides the angle into two parts name the parts angle 1 and angle 2 respectively

Now, angle 1 = 20° (by alternate interior angles)

Also, angle 2 = 30° (by alternate interior angles)

hope this helps
