Answer:

∠ Z = 80°

Explanation:

Since the quadrilaterals are similar , then corresponding angles are congruent

the sum of the angles in a quadrilateral = 360°

sum the angles in FECG and equate to 360°

∠ F + 100° + 60° + 120° = 360°

∠ F + 280° = 360° ( subtract 280° from both sides )

∠ F = 80°

∠ Z and ∠ F are corresponding angles , then

∠ Z = ∠ F = 80°
