Question 187000:
Lines A and B are parallel and are cut by the tranversal show. Determine the measures of angles 1 through 7:
This is what I came up with and I'd like it to be double checked before turning it in.
angle 1 = 120 degrees
angle 2 = 60 degrees
angle 3 = 60 degrees
angle 4 = 120 degrees
angle 5 = 60 degrees
angle 6 = 120 degrees
angle 7 = 60 degrees....I'm hoping I was headed in the right direction at least:-)
