Find the remaining angles and side if they exist. If no triangle exists, say "No triangle" a= 4 b=1 y=100 degrees Please help! and I am also assuming that sides a and b form to make angle y, which would make it a triangle, I think.

Does the example state that y is the angle between a and b or not? If not, you have to analyse all the three cases. Draw a sketch, that helps a lot. Two cases are possible, one is not. It is because the biggest angle is always in front of the biggest side, and b=1 can't be the biggest.

case 1: y = the angle between a and b case 2: y = the angle between a and c case 3: y = the angle between b and c
