Answer:
The answer is 145°
Explanation:
Angle 3 and 4 make a right angle (90°) Subtract 55 from 90.
90-55=35
Angle 3 and Angle 1 are vertical angles, hence they have the same measurement.
Angle 1 is 35°
Angle 1 and 2 make a 180° angle. Subtract 35 from 180.
180-35=145
The measurement of angle 2 is 145°
