Answer:
x = 90
y = 58
z = 32
Explanation:
∠x + Interior angle of the square = 180° (Sum of angles on a straight line)
∠x + 90° = 180°
∠x = 90°
∠x + ∠y + 32° = 180° (Sum of angles in a triangle)
90° + ∠y + 32° = 180°
∠y = 180 - 90° - 32° = 58°
∠y + ∠z + Interior angle of the square = 180°
58° + ∠z +90° = 180°
∠z = 32°
∠x = 90°
∠y = 58°
∠z = 32°
