Find the geometric proof
GrogVix [38]

Answer:

See Explanation

Step-by-step explanation:

Line l is bisector of MO... (given)

\therefore MN = NO.... (1)

\because MN + NO = MO..(M-N-O)

\therefore NO + NO = MO..[From \:(1)]

\therefore 2NO = MO

\therefore NO = \frac{1}{2} MO

\therefore NO = \frac{1}{2}\times 24..(\because MO=24)

\therefore NO =12

Thus Proved
