OpenStudy (anonymous):
are there any conditions for o and h
OpenStudy (anonymous):
CO is the mediane and CH the height.
OpenStudy (anonymous):
then o is the mid point

Yes.
OpenStudy (anonymous):
then it comes in points
is it okay?

I have to find the other lenght with some formulas.
Should I write them ?
OpenStudy (anonymous):
*lenghts
OpenStudy (anonymous):
what formula's

OpenStudy (anonymous):
h^2=b'*c'
b^2=b'*a or c^2=c'*a
a^2=b^2+c^2
h=bc/a
OpenStudy (anonymous):
if h=bc/a
then bc=ah
then ah=28
OpenStudy (anonymous):
are abc the lenghts of the sides or the points
write it with clarity

0b=26.5 as it is the mid point
OpenStudy (anonymous):
28^2=oc^2+26.5^2
784=0c^2+702.25
0c^2=784-702.25
0c^2=81.75
0c=9.04
OpenStudy (anonymous):
oh=0b/2
oh=26.5/2
oh=13.25
OpenStudy (anonymous):
ha=oh+oa
ha=39.75
OpenStudy (anonymous):
a^2=b^2+c^2
This formula only works with a triangle with right angles.
