The sum of angles of a triangle =180°

Angle 1 + Angle 2 + Angle 3 = 180°

Subtract ( Angle 1 + Angle 2 ) to both sides

Angle 3 = 180° - ( Angle 1 + Angle 2 )

Angle 3 = 180° - ( 30° + 110° ) = 180° - 140° = 40°

Angles on one side of a straight line= 180°

In this case line 2 - 3 is a straight line so:

Angle 4 = 180° - 40° = 140°
