jhonyy9 (jhonyy9):

do you know formula for volum ?

jhonyy9 (jhonyy9):

are you here ?

jhonyy9 (jhonyy9):

so you dont like to cooperate ?

OpenStudy (anonymous):

L X W X H?

jhonyy9 (jhonyy9):

ok you know L and W so how to calculi H ?

OpenStudy (anonymous):

Sorry, my computer is slow.

OpenStudy (anonymous):

I'm not sure..

jhonyy9 (jhonyy9):

ok ,so how you calculi H ?

jhonyy9 (jhonyy9):

there is an equilaterale triangle with sides 3" H is the altitude of this triangle can you calculi it ?

OpenStudy (anonymous):

No...

jhonyy9 (jhonyy9):

|dw:1375295729753:dw|

jhonyy9 (jhonyy9):

what is the measure of angles there ?

OpenStudy (anonymous):

90 degrees?

jhonyy9 (jhonyy9):

what is the property of angles of an equilateral triangle ?

jhonyy9 (jhonyy9):

not is 90

OpenStudy (anonymous):

Sorry, I'm horrible at geometry. I'll just have to have my mom explain it, thanks anyways.

jhonyy9 (jhonyy9):

no i will help you

jhonyy9 (jhonyy9):

moment

jhonyy9 (jhonyy9):

so what is the sum of angles of a triangle ?

OpenStudy (anonymous):

270?

jhonyy9 (jhonyy9):

no just 180 degree

OpenStudy (anonymous):

I know that the area is 9 sqrt(3) / 4

OpenStudy (anonymous):

right?

OpenStudy (anonymous):

and the height is 6"... right?

jhonyy9 (jhonyy9):

and in case of an equilateral triangle there are 3 sides so what mean that there are 3 equale angles so than you just divide 180 by 3 and will get the maesure of an angle what will be 60 degree

jhonyy9 (jhonyy9):

how you get 6" ?

OpenStudy (anonymous):

From the graph I first had...

OpenStudy (anonymous):

https://media.glynlyon.com/g_geo_2012/8/soltri.gif

OpenStudy (anonymous):

I'm thinking area x height will give me the answer

jhonyy9 (jhonyy9):

|dw:1375296202318:dw|

OpenStudy (anonymous):

(9 sqrt(3) / 4) x 6 = 27 sqrt(3) / 2

OpenStudy (anonymous):

I'm trying to do my previous question https://media.glynlyon.com/g_geo_2012/8/soltri.gif

jhonyy9 (jhonyy9):

how you have got this result ? you dont like rewriting here your calculi ?

OpenStudy (anonymous):

I'm doing it on paper. I have my answer now. Thank you.

jhonyy9 (jhonyy9):

ok good luck
