Question

p and q are opposite angles of parallelogram if p equal to 70° then R equals to what?​

Answer 1

Answer:

<Q=<S (alternative interior angle)

<Q=50,

So <S=50

In parallelogram PQRS

<S+<R+<Q+<P=360

<S+<R+100=360

<S+<R=260

Since <S =<R

<S=<R=260/2=130

<R=<QRP+<PRS

130=<QRP+70

__________

<QRP=60°

<SPR=<QRP

<SPR=60
