Question

............. Ausus v e
A tangent PQ at a point P of a circle of radius 5 cm meets a line through the centre O ata
point so that OQ=13 cm. Find length of PQ-​

Answer 1

Answer:

we know that tangent at centre circumference make an angle of 90° .

so,

in Rt∆ OPQ,

OQ = 13cm (Given)

OP = 5cm (Radius)

By pythagoras theoram :-----

PQ = √OQ²-OP² = √13²-5² = √144 = 12cm (Ans)

(Mark as brainlist)

Answer 2

Answer:

by pathagurous theorem

radius is 5 cm

hipotenus is 13

13^2=5^2+ pq^2

√144=12 ans
