OpenStudy (anonymous):

|dw:1424352351371:dw|

OpenStudy (anonymous):

ok use sine law on this

OpenStudy (anonymous):

um its 30-60-90 rule right

OpenStudy (anonymous):

|dw:1424352570760:dw|

OpenStudy (anonymous):

yeah, 30-60-90

OpenStudy (anonymous):

short=5 long=_______

OpenStudy (anonymous):

i dont know this rule

OpenStudy (anonymous):

is there a question to go with the picture?

OpenStudy (anonymous):

short=5 long=_______

OpenStudy (anonymous):

the ratios of a 30 - 60 - 90 right triangle are \[1:\sqrt3:2\]

OpenStudy (anonymous):

if the short side is 5, then the long side is \(5\sqrt3\)

OpenStudy (anonymous):

wha??????????

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

is there something confusing about that? if so, what?

OpenStudy (anonymous):

your first post with the ratio

OpenStudy (anonymous):

hmmm unconfuse yourself the rations are one to the square root of three to two i.e. \[1:\sqrt3:2\] that means for example if the short side is 10 then the long side is \(10\sqrt3\) and the hypotenuse is \(20\) or if the hypotenuse is 4 then the short side is 2 and the long sides is \(2\sqrt3\)

OpenStudy (anonymous):

k undrstand now
