Answer:
59
Explanation:
Opposite angles are equal
C or KCG isn121
Straight line angle is 180
YCG + GCK = 180
YCG = 180- 121
Another method
All the four angles at a point is 360
YCH + HCK + KCG +YCG is 360
C is 121
121 + X + 121 + X = 360
2X + 242 =360
Subract 242 from both sides
2X = 118
Divide both sides by 2 = 59
