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.. |dw:1377791869950:dw|

OpenStudy (anonymous):

||dw:1377791988664:dw|

OpenStudy (anonymous):

|dw:1377792136232:dw|

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

OpenStudy (anonymous):

Yes.

OpenStudy (anonymous):

then it comes in points is it okay?

OpenStudy (anonymous):

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

OpenStudy (anonymous):

|dw:1377793043425:dw|

OpenStudy (anonymous):

k now it is fine wait for a min i'l give you the answer

OpenStudy (anonymous):

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.

OpenStudy (anonymous):

ya CHB,CHO,COB,COA are right angle triangles

OpenStudy (anonymous):

Not COB and COA.
