Answer:

180

Step-by-step explanation:

Angle 2 and 1 make a straight line that adds up to 180 degrees.

Answer:

1 = 120°, 2 = 60°

Step-by-step explanation:

All angles of a triangle add to 180°. Adding the other angles gets 60°. 180° - 60° = 120°. Lastly, 1 added with 2 will make 180°, so 180° - 120° = 60°
