Question

2. LM is a chord of a circle with centre C. If
CN parallel LM, MC produced intersects the circle at P
and if PL = 10 cm, then the length of CN will be
(a) 8 cm
(b) 5 cm
(c) 6 cm
(d) 9 cm​

Answer 1

Answer:

t

In the given figure AB is a chord of a circle, with centre O, such that AB=16cm and radius of circle is 10 cm. Tangent at A and B intersect each ...

Answer 2

Step-by-step explanation:

From figure ,

Tangent drawn from outside point to circle at two points have equal length.

i.e. PA=PB

⇒PL+LA=PN+NB

⇒

PL+LM=PN+NM

{∵LA=LM∵NB=NM}
