Question

I don't get it at all could you go step by step with me

Answer 1

∠e = 110°
What is ∠b?

To find this, we look at our angles. ∠e and ∠b are what we call alternate exterior angles. These are basically just angles on the outside of the traversals, when added with each other, equal 180°. This may sound complicated, but it is fairly easy.

All you have to do is take 180 and subtract it from ∠e.

So, 180° - 110° = 70°

So, ∠b is equal to 70°

Your answer is B) 70°

~Hope I helped!~

Answer 2

Okay, so if e=110, then so does c, because they are Alternate Interior angles. If c=110, then so does a, because they are Alternate Exterior. Angles a and b are on a straight line, which equals 180 altogether, and 180-110 is 70, so the measure of angle b is 70.
