how are you getting 1/2(b-a)?
jimthompson5910 (jim_thompson5910):
how did you get 1/2(b-a) on your paper
jimthompson5910 (jim_thompson5910):
yes I know, but on your paper, how did you get 1/2(b-a)
you wrote it down
jimthompson5910 (jim_thompson5910):
which one
jimthompson5910 (jim_thompson5910):
the longer base is 2a units
the shorter base is _____ units

you sure?
jimthompson5910 (jim_thompson5910):
2a is the longer base, a is the length of half of the longer base
jimthompson5910 (jim_thompson5910):
that does not tell us the length of the shorter base
jimthompson5910 (jim_thompson5910):
you tell me
jimthompson5910 (jim_thompson5910):
hmm something seems missing here, let me think

how are you getting b?
jimthompson5910 (jim_thompson5910):
yeah something seems to be missing
jimthompson5910 (jim_thompson5910):
if you knew the shorter base, then you could figure out where T and W are
jimthompson5910 (jim_thompson5910):
but it doesn't give out that info
jimthompson5910 (jim_thompson5910):
no we have no guarantee that the shorter base is half of the longer base

it's missing info, there's no way anyone can know for sure
jimthompson5910 (jim_thompson5910):
if the shorter base was 2b units
then W would be at (b,c) since you go out b units to the right, then up c units
jimthompson5910 (jim_thompson5910):
but this piece of info isn't given, so you can't answer the question
jimthompson5910 (jim_thompson5910):
yep that's IF the shorter base is 2b units
