Dear pallavi


r=sinθ+cosθ      and       r=2sinθ


solve the curve for point of intersection


θ =45   and r =√2 


 


now  curve  r =2sin45


and              r =sinθ+cosθ


                        =√2 sin(θ+45)


                        =√2 sin(90)


clearly the angel between them is  90-45 =45
