Let anglePOR=5x & angleROQangle=7x Then angle POR + angle ROQ =180degree(linear pair axiom) Then, 5x+7x=180 DEGREE So,12x=180 degree x=180/12 x=15 degree (By the property, Vertically opposite angle AnglePOR =angleSOQ &angleROQ =anglePOS) So, AnglePOR =angleSOQ=15*5=75 degree & angleROQ =anglePOS=15*7=105 degree
