Question

Pls give correct answer for this question.​

Answer 1

Step-by-step explanation:

first draw parallel line qo which is parallel to AB and CD hence, qo bisect angle q

angle BPQ=1/2angle q(alt.angle)

but,1/2angle q=angle r

Therefore angle p+ angle r=180°

but angle r=angle 1/2angle q

2angle r =angle q

p+r=180°(l.p)

Hence,p+q-r =180°
