Question

please give me answer

Answer 1

Heya♥️♥️

As, we know that the lenghts of tangent s drawn from an external point to a circle are equal,
. p is an external point so,

PA=PB.


AGAIN,
L and N are external point so, NB=NM and AL=LM-------1


as, PA=PB so we can write PL+LA=PN+NB

and by 1 we can write PL+LM=PN+NM



Hence, proved..


Thanks♥️♥️♥️♥️
