Question

PQRS is a cyclic quadratic surch that PR is the diameter of the circle . if angle PQR = 50° and angle SPR=60° then angle QRS=_______​

Answer 1

Answer:

60

Step-by-step explanation:

in a cyclic quadrilater

PQR= 50, SPR= 60 - - - - - - given

QRS= ?

PR is diameter.

60+ 60= 120

And

the sum of two angles is 180 i.e 180-120 = 60

I.e. QPS = 60 ,
