So I am doing a trig question that ended up with 11/Sin100 = 8/SinX, I don't know where to go from here. I'm grateful for any help.

If you could post a picture of the full question with your working up to then, then we can see where to go from there.

Pretty sure you made a mistake
When working out angle it is not a/sin A = b/sinB
It is the other way around so sinA / a = sinB / b

So in your case: sinX / 8 = sin100 / 11

So you get sinX / 8 = ans
So sinX = ans * 8
So sinX = 0.7162238204
But when it is angles you need to do inverse sin
So you get
Sin^-1 (0.7162238204) = 45.74358566

So the angle is 45 or 46 degrees depending on question

Hope this helps.

These are equivalent statements
It does not matter which way this relation is written.
