Answer:
Step-by-step explanation:
now in PARALLELOGRAM ECLU
∠LCE + ∠ECL = 180 (ADJANCENT ANGLE IS 180)
70 + ∠ECL = 180
∠ECL = 110
NOW IN PARALLELOGRAM ECLU
∠ECL + ∠CEU = 180 (ADJANCENT ANGLE IS 180)
110 + ∠CEU = 180
∠CEU = 70
NOW IN PARALLELOGRAM KSIR
∠SKR + ∠KSI = 180
120 + ∠KSI = 180
∠KSI = 180 -120
∠KSI = 60
NOW IN ΔOES
∠OES = 70
∠OSE = 60
∠SOE = X
∠OES + ∠OSE + ∠SOE = 180
X + 70 + 60 = 180
X + 130 = 180
X = 50°
