Answer:
100°,110°,70°,80°
Step-by-step explanation:
The sum of all interior angles of a quadrilateral is 360°
∠A +∠B + ∠C + ∠D = 360°
100 + 70 + 80 + ∠D = 360
∠D = 360 - 100 - 70 - 80 = 110°
Hence the missing interior angle is 110°
∠X = 180 - 80 = 100°
∠Y = 180 - 70 = 110°
∠W = 180 - 110 = 70°
∠Z = 180 - 100 = 80°
