Answer:

angle 1 = 50°

angle 2 = 70°

angle 3 = 50°

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°
