Try establishing a relationship between angles QSR and QOR

Do you know what it means for a quadrilateral to be cyclic?

[olive token]

well qor = 2x

PRQ = X
PRS = 180-2x
QSR = 180-(180-2X)
=2x

[olive token]

all 4 vertices lie on cricumeference

so QSR = QOR = 2x

idk what next

[pearl yacht]

More like opposite angles add to 180 degrees. But sure.

[olive token]

Yeah

and that

what would i do now

[pearl yacht]

Prove such.

Opposite angles add to 180.

[olive token]

Im not sure how do thattho

[pearl yacht]

And therefore?

Try finding QSO
