what if we hane an angle like 177

i mean an obtuse angle or a reflex................

how can we trisect an angle

am in 9th which maths books should be referred for clearing RMO

should i read specific books on no.theory,geometry etc...

 can frame ur roll no.

the 9 digit no. consists of 4 digits of school code,2 of class and 3 of individual code.u can get ur school code from ur school and frame you roll no.

ABCD11EFG

ABCD-school code

EFG-ur code

u can form ur code(the 3 digits) by hit and trial starting from 001

or better ask ur school to give u ur rollno. i suppose they maintain the lists.

or check if the site provide school wise results then a school code will suffice

but i think they dont.......................

hw many of u gave NSO.any ways the result is out.

www.sofworld.org is the site

plz tell ur ranks also

if we talk about the possibility of life in ur solar system we should expect only primitive(or even a bit advanced) microbes.....expecting intelligent life forms wud be foolish........but this wud be a breakthrough.....scientists are expecting some some form of life on saturn's moons like titan and encelidus but without success (till now)

however if we talk abt intelligent life forms like humans that is possible only in exo planetery systems.if we consider Frank Drakes equation for this there may be millions of worlds like urs out there where life has developed and evolved and some creatures like us have been able to withstand the test of time.

(in fact the main aspect of ET is even if life  evolved to humans is it being sustained)

hope it is clear u may rate...plz
