Can anyone help and tell me the measure of all 20 angles? I'm struggling. Some of them I figured out, but I'm not 100% confident that they are correct. This is a Geometry problem.

Step-by-step explanation:

When two lines cross, the angles opposite each other are equal (they are called vertical angles--different from how we use the word vertical in other math classes) The angles next to each other add up to 180° (supplementary angles)

All the angles in a triangle add up to 180°

Perpendicular lines makes right angles, those are 90°

When you have parallel lines and another line crossing them, you get 8 angles, but 4 if them are all the same. Subtract the measure from 180 and you have the measure of the other four angles. Look for a Z shape; the angles tucked inside the Z are alternate interior angles and they are equal. The alternate interior angles and their vertical angles are what make up the 4-pack of equal angles.

These are all the rules you need to know to find all 20 of the angles in your question. See images

b) well because you get well

idk man good luck man
