    \[\frac{ a }{ \sin A }=\frac{ b }{ \sin B }=\frac{ c }{ \sin C }\]where a,b,c are sides and A,B,C are the angles opposite the corresponding sides

    \[\frac{ x }{ \sin 87 }=\frac{ 21 }{ \sin 37 }\]

    You don't have any right angles. "hypotenuse" doesn't mean anything for this triangle.

    when you don't have a right triangle think law of sines or law of cosines

    ohk so i get rid of the 37 first right?.... by multiplying?

    You calculate the values for sine and then you solve for the missing item. In this case, it is only a simple multiplication.

    No, there is not 87 or 37. You must first calculate the sine of those angle measures.
