Answer:
Since angles 5 and 1 are supplementary (meaning they equal to 180°), angle 1 is equal to 35° (180° - 145° = 35°)
Angles 1, 2, and 3 are also supplementary angles since they equal to 180°. We know that angle 1 = 35°, and angle 3 = 60°. So all we have to do to get the measure of angle 2 is to add angles 1 and 3 and subtract it to 180°.
35° + 60° = 95°
180° - 95° = 85°
Therefore, angle 2 is equal to 85°.
