In a right triangle named BAC, the hypotenus BA is 53 cm, AC is 28 and BC is 45. Find out HA, HO, OB, HC, CO...

OpenStudy (amriju):

incomplete question...u mentioned no specifications about point O and H

OpenStudy (anonymous):

H is the height and O is the median.

OpenStudy (anonymous):

CO is 26,5 and AO and OB too.

hero (hero):

What does 26,5 represent?

OpenStudy (anonymous):

cm.

hero (hero):

26.5 cm

hero (hero):

in US, you put a point between whole number and decimal

hero (hero):

The reason for this is because (26,5) can be mistaken as an (x,y) point.

OpenStudy (anonymous):

I put a comma.

hero (hero):

I know what you put. I explained why you shouldnt.

OpenStudy (anonymous):

O.K.

hero (hero):

If O is the median, then BO and OA are equal.

OpenStudy (anonymous):

Yes.

hero (hero):

But you haven't drawn it in a way that reflects that.

hero (hero):

You haven't included all of the given info.

hero (hero):

there should be some indication of which segment is perpendicular to BA

OpenStudy (anonymous):

|dw:1377790333592:dw|

hero (hero):

That's a lot better.

hero (hero):

Does it give you tick marks to indicate if segments are congruent?

OpenStudy (anonymous):

It says :Calculate the lenghts of all the lines knowing that AO=26.5 cm and AC=28 cm.

hero (hero):

There's still more info you're not including. You should scan whatever it is you're looking at that way I can see it.

OpenStudy (anonymous):

It is in french.

hero (hero):

I see. Well, I definitely don't know French. However, you can at least scan the diagram.

OpenStudy (anonymous):

There is no diagram but there are some formulas I know.

hero (hero):

If there's no diagram, then how do you know what it looks like?

OpenStudy (anonymous):

There is a triangle but it was from another question.

OpenStudy (anonymous):

There are no indications on it.

hero (hero):

Does it indicate whether or not AH is congruent to HO?

hero (hero):

That's a lot better.

OpenStudy (anonymous):

Congruent ?

OpenStudy (anonymous):

I have learned math in German and French but not English, sorry

OpenStudy (anonymous):

You can explain in English.

OpenStudy (anonymous):

No they are not.

OpenStudy (anonymous):

I looked on the internet what it means..

hero (hero):

Okay.

hero (hero):

I'm not sure if I can help you with this then.

hero (hero):

Actually, you could find angles of the bigger triangle to help.

OpenStudy (anonymous):

These are the formulas I know : h^2=b'*c' h=bc/a a^2=b^2+c^2 b^2=b'*a works with c too

hero (hero):

I'm not sure if I can help you with this then.
