Question

The idea is to make RHS similers to ( 2 mathrm{HS} ) by taking a number ( n^{prime} ) as standered and then hitting the equetion by trial and error. soon you'll find that,
[
100 quad underline{n=19}
]
we get ( angle H S=R H S )
hence ( underline{n=19} ) is the correct answer.

# 10. Ifn+2Cg: 1-2P4 =57:16, find n. 11. If 2
