Answer:
1. I don't know how to solve that sorry :(
2. B. It is a diameter
3. 30° = q
4. I don't know sorry :(
Step-by-step explanation:
1. I don't know how to solve that sorry :(
-----------------------------------------------------------
2. B. It is a diameter
------------------------------------
3. All triangles = 180°
180° = 60° + 90° + q
180° = 150° + q
180° - 150° = 150° - 150° + q
30° = q
180° = 60° + 90° + 30°
180° = 150° + 30°
180° = 180°
------------------------------------------
4. I don't know sorry :(
