The way you'd set it up would be sin55º/12=sinB/14 (you could also flip the equation so that 12/sin55º=14/sinB, you'll get the same answer either way). Multiply out so that its 14•sin55º=12•sinB, or 11.47=12•sinB. Divide both sides by 12 so that it looks like .96=sinB, then take arcsine of both sides (arcsin= x=sin^-1 theta+360n or x=180- (sin^-1 theta)+360n), which should give you about 72.88º and 107.12º.
ANSWER
The value of x is
EXPLANATION
We want to solve the equation,
The first step is to add 4 to both sides of the equation to obtain,
We simplify the right hand side to obtain,
We now square both sides of the equation to obtain,
This simplifies to
We solve for x to obtain,
This implies that,
Your answer is x = -250
