Insufficient data for a meaningful answer

Answer 2

Triangles angles always add up to 180 degrees. Add the known degrees togther and subtract from 180 to get what the finall angle is. For example, if a triangle has two known angles, 50  degrees and 80 degrees add them and get 120 then do 180-120 to get the missing angle. hope that helps sorry if it's confusing, Just ask if i need to explain more :)
