(20 points, please help!) Using the diagram, what are the measures of angles 1, 2 and 3?

Answer:
angle 1 = 50°
angle 2 = 70°
angle 3 = 50°
Step-by-step explanation:
We know the top triangle equals 180 degrees.
angle 1 + 60 + 70 = 180
angle 1 + 130 = 180
angle 1 = 50
Because of parallel lines, we know that opposite angles will be equal.
What I mean by this is that angle 1 = angle 3 and angle 2 = 70 degrees.
angle 1 = 50°
angle 2 = 70°
angle 3 = 50°
