Answer:
170° and 52°
Step-by-step explanation:
∠ WZY and ∠ YZA are adjacent angles and sum to 180° , that is
∠ WZY + 10° = 180° ( subtract 10° from both sides )
∠ WZY = 170°
The sum of the angles in a quadrilateral = 360°
sum the angles and equate to 360
∠ XYZ + 170° + 38° + 100° = 360°
∠ XYZ + 308° = 360° ( subtract 308° from both sides )
∠ XYZ = 52°
