Question

ABQC and PQRS are parallelograms. Find x.​

Answer 1

Answer:

x=20°

Step-by-step explanation:

A=CQB=80° (opp angles of ||gm are equal)

similarly, P=SRQ=60°

SRQ+QRA=180° (Linear pair)

60°+QRA=180°

QRA=120°

QRA=RQP=120° (Alternate angles)

PQC+CQR+RQB=180° (linear pair)

120°-x+x+80°-x=180°

200-x=180°

x=20°

feel free to correct me if I'm wrong

kinda wrote this in a hurry:)
