Question

AB is parallel to CD angleBPQ=140 degrees and angle QRD =150bdegrees find angle PQR​

Answer 1

Step-by-step explanation:

now ,

draw a line parallel to ab and cd at point q

because of this the angle q is divided into 2 angles

mark the line as EF

here abllef ; pq is transversal.

at point p linear pair is formed

140+X=180

X=40°

q1= 40°( alternate angles)

now

efllcd; qr is transversal

at point r linear pair is formed

X+150=180

X=30°

q2 = 30°(alternate angles)

angle pqr= q1 +q2

= 40+30

=70°
