One solution: Two angles of the triangle can be found, since we know their supplement angle counterparts. The first one is 50 degrees, and the second angle is 46 degrees. Thus the final angle has a measurement of 180 - 46 - 50 = 84 degrees. However, "x" is the supplement of the third angle, so 180 - 84 = 96
"x" can also be the sum of the two other angles within the triangle, or 360 - 134 -130, cause all interior angles of any polygon always add up to 360.
