Hope this helps you :)

1. x = 180° - 90° = 90° (Linear pair)

z = 180° - 30° = 150° (Linear pair)

In a triangle exterior angle is the sum of the two opposite interior angles,

y = 30° + 90°

y = 120°

x + y + z = 90° + 150° + 120° = 360°

(You already know that the sum of exterior angles of a triangle is 360°)

2. x = 180° - 120° = 60°

y = 180° - 80° = 100°

z = 180° - 60° = 120°

Fourth interior angle = 360° - 120° + 80° + 60° = 100° (Sum of all the angles of a quadrilateral is 360°)

w = 180° - 100° = 80°

x + y + z + w = 60° + 100° +120° +80° = 360°

(You already know that the sum of exterior angles of a quadrilateral is 360°)
