To find the measure of side B, we need to use the fact that the sum of all angles in a triangle is 180 degrees.
Therefore, we can set up the equation:
128 + (X - 61) + C = 180
Simplify the equation:
128 + X - 61 + C = 180
X + 67 + C = 180
Now we know that X + 67 + C = 180, and we know that C = 180 - X - 128. C is the measure of the third angle in the triangle.
Substitute C = 180 - X - 128 into the equation X + 67 + C = 180:
X + 67 + 180 - X - 128 = 180
67 + 52 = 180
119 = 180
Therefore, there is no solution for this problem as the equation does not hold true.
The full degree is 180 degrees..
Side A is 128 degrees.
Side B is (X - 61) degrees.
Solve for x
