RobinHez:
pukka36 score 5 out of ....?
Olodo RaAPata, oju eja lo mo je.....
hahahahahahahahaha...tis the happiest day of my nairaand life!b!b!

lordkvng:
your number 71 is wrong, sucrose is not a reducing sugar, there fore it has no effect on fehlings solution... check your chemistry textbook well

RobinHez:
all of u shouting 24 sides....if i give u e-slap, ur eyes will open to see the 'help' disclaimer i put on the question...


show me workings jhor...

n-2)180= sum of interior angles (n-2)180= n(165) 180n - 360 =165n 180n-165n = 360 15n = 360 n =360/15 n=24

Ada96:
interior angle =165 degree sum of an int. n ext =180 degree so one exterior angle will be 180-165=15 also sum of exterior angle is 360 degree n with one exterior angle equal to 15 degree therefore the no of sides will b 360/15 which is equal to-----24sides
that's how I got my own o

Pukka36:
Lol! I pray oh...nt when M nt sleeping

I already got the correct answers...


It's nt bragging sha..buh Kemixtry is my forte and 5 wetin sef

RobinHez:
thanks...but where did u see th n dat u put on the RHS?

RobinHez:
i don't understand...u scored 5 because u were sleeping

RobinHez:
i don't understand...u scored 5 because u were sleeping

Pukka36:
I didnt score 5...I already compared mine with the guy that had 18.



How on earth will I score five

Pukka36:
Yeye



Jejely compare my answers with His underlined!



I got 14 and T'is a far cry from 5 so no biggie...And some answers r questionable!
