Question

In the given figure pQ is tangent at point Rof a circle with centre o and angle QRB=30°then angle PRA is​

Answer 1

From figure, Given that

∠TRQ=30

∘

∠TSR=∠TRQ=30

∘

(by Alternate segment therom).....(i)

∠TRS=90

∘

(Angle in semi circle)..............(ii)

From (i) & (ii) ∠RTS=60

∘

(Angle sum property in △SRT)

∴∠PRS=∠RTS=60

∘

(by Alternate segment therom)
