OpenStudy (anonymous):

write down sin (20°) = a/h

OpenStudy (anonymous):

solve for h \[\frac{ 1 }{ \sin(20°) }=\frac{ h }{ a }\]

OpenStudy (anonymous):

you know the value of a, plug it in to your calculator

OpenStudy (anonymous):

\[=\frac{ 1*a }{ \sin (20°) } = h \]

OpenStudy (anonymous):

|dw:1394606306808:dw|

OpenStudy (elisaneedshelp):

Wait i didnt get how to plug it into the calculator

OpenStudy (anonymous):

the orientation of the right triangle can rotate and the position of the angle can also change an example |dw:1394606359686:dw|

OpenStudy (anonymous):

NOTICE that the opposite side is always across the angle and the adjacent side is always next to the angle and of course as you may already know, the longest side is the hypotenuse the mnemonic SOH CAH TOA does not mean anything if you don't know how to identify your angle of reference and the corresponding sides. this is why I took the time to draw and illustrate how to do just that

OpenStudy (elisaneedshelp):

Ok i understand that

OpenStudy (elisaneedshelp):
