Question

Please answer this photo its urgent​

Answer 1

Answer:

Since its urgent i wont explain

1. x = 40°
2. y = 30°, x = 150°

Answer 2

Answer:

1. 180° - 130° = 50° ( straight angle )

x + 90° + 50° = 180° ( angle sum property of ∆)

x + 140° = 180°

x = 180° - 140°

x = 40°

2. 80° + 70° + y = 180° ( angle sum property of ∆)

150° + y = 180°

y = 180° - 150°

y = 30°

x + y = 180° ( straight angle )

x + 30° = 180°

x = 180° - 30°

x = 150°

Hope it helps you.
