Answer:
122
Explanation:
Angle W + Angle A = 180
This is because it's supplementary (adds to 180)
Angle W= 127
180-127=53
Angle A= 53
Angle B= 69
All angles in triangle (get it, tri angle?) add to 180
If we know that any 2 angles we can figure out the 3rd
so 53+69= 122
Triangle sum 180 = 180 - 122
= 58
Angle C = 58
Angle C + Angle X = 180 (B/c it's on a straight line which is = to supplementary angles
Angle X = 180 - Angle C
= 180 - 58
= 122
