I can help with this!  Look at your picture.  You have an angle and the side opposite that angle, and the measure you are looking for is actually the hypotenuse of the right triangle.  The sin of an angle is the side opposite the angle over the hypotenuse.  So what you have is$$\sin40=\frac{ 128 }{ d }$$You need to rearrange this so you have d alone, cuz after all that's what you're solving for!  So...$$d=\frac{ 128 }{ \sin40 }$$I believe they gave you the amount in the table for the sin40, but my calculator gives it to me as .6428.  So divide 128 by .6428 and you get your answer!
