Question

PQ and PR are two chords in 0 central circle The tangents drawn at points Q and P intersect at point s. If QSR = 70, what is the value of QPR?​

Answer 1

$\huge\color{purple}{Solution}$

Here ∠OSQ=∠OQS=90 o

−50 o =40 o

and∠RSQ=∠SRO=90 o

−60 o =30 o

∠QSR=40 o +30 o =70 o .

Answer 2

Answer:

$solution$

Here <OSQ=<OSQ=90 o

-50 o = 40 o

and <RSQ =< SRO = 90 o

-60 o = 30 o

<QSR= 40 o + 300 = 70 o .

hope it help uh!!☺✌࿐
