Question

what is the answer ???​

Answer 1

Answer:

Join OP and OQ

Given ∠PRQ=120

∘

∴∠POQ=60

∘

(supplementary angles)

Also, we have PR=RQ (equal tangents) and ∠OPR=90

∘

(radii is perpendicular to tangent)

Now,

OR

PR

=cos60

∘

=

2

1

(∠ROP=30

∘

and ∠PRO=60

∘

)

⟹OR=2PR

⟹OR=PR+RQ

Hence proved
