Question

In quadrilateral PQRS, LS = 75 degree, LP = 50 degree, LQ =100 degree.Find LR?

Answer 1

hey here is your answer
---------------------------------
we know that ---->>>
total value of quadrilateral angles are = 360 degree

angleS + angleP + angleQ +angleR = 360degree

75 + 50 + 100 + angleR = 360degree
225degree + angleR = 360degree
angleR = (360-225)degree
angleR = 135degree

I hope it will help you..
