Q.2 (A)(2) In the following figure chord MN and chord RS intersect at point D. If RD = 15, DS = 4, MD = 8, find DN by completing the following activity :
[Figure: circle with chords MN and RS intersecting at D inside the circle.]
Activity :
∴ MD × DN = ____ × DS .............. (Theorem of internal division of chords)
∴ ____ × DN = 15 × 4
∴ DN = ____ / 8
∴ DN = ____
