Question

6. If PQ is a tangent to a circle of radius 5cm and PQ = 12 cm, Q is point of contact, then OP
is​

Answer 1

Answer:op=13 cm

Step-by-step explanation:pq =12 cm, oq=5 cm

In the circletter makes an right angle triangle

(Since radius perpendicular to tangent makes an 90°)

In triangle open, <p=90° By the pythagoras therom

Side^2+Side^2=Hypotenuse ^2

5^2+12^2=Hypotenuse ^2

25+144=Hypotenuse ^2

169=Hypotenuse ^2

Hypotenuse =root over (13 )^2

Hypotenuse =13

There fore op=13 cm
