Question

PQRS is a parallelogram. If angle Q=50, then angle P =?​

Answer 1

p=130

1. R=50(vertically opposite angles are equal)
2. P=180-50=130. (corresponding angles are supplementary

Answer 2

Answer:

Sum properly of parallelogram is 360.

Angle Q=50

Angle S=50 (vertically opposite angle

Angle P+Q+R+S=360

Angle P+50+R+50=360(P=R vertically opposite angle)

now,P+50+P+50

2P+100=360

2P=360-100

2P=260

P=130.
