ok?

OpenStudy (anonymous):

\[\sin 30=\frac{ 10 }{ x }\]

OpenStudy (anonymous):

I'll try, so what's the question?

OpenStudy (anonymous):

solve for x

OpenStudy (anonymous):

x = 10/sin30

OpenStudy (anonymous):

and if you remember sin30 = 1/2 then... x = 10/(1/2) = 20

OpenStudy (anonymous):

what about sin39=9/x
