Answer:

B. m1 = 120

Explanation:

Since there is a right angle at 3 and 4, you can conclude that both those angles are 90 degrees as well.

Additionally, using the straight line rule for angle 5, 180 - 150 = 30

Now to calculate angle 2, you take both angles 3 and 5 and subtract from 180:

180 - 90 - 30 = 60

Using the straight line rule again for angle 1, 180 - 60 = 120

You can conclude that m1 = 120 degrees
