Question

PQRS is a Parellogram in which the diagnols PR and SQ meet each other at O if angel OPQ = 45 degree angle PSO=30Degree angle SOR=70degree find angle PQS and angle SQR​

Answer 1

Answer:

abcd is parallelogram

so angle sqr=30°(alternate angle as pq is parallel to sr)

and angle pqs=65°(because angle poq is eqall to angle sor due to vertically oppposite

and so we know that sum of angles of triangle is 180 degrees so angle pqs =45+70-180

=65°)
