Can someone help me with my homeworkkk

1. they're vertical angles but the The missing angle is 140

2. there's no relationship being displayed because there's no image

3 theyre vertical angles

4 is 51

5 is 41

6 is 59

Step-by-step explanation:

All you need to do to find the missing angles is subtract from whatever. so the first one is a straight line so all you would do is 180-40 for the one that kind of looks like an x just know they're going to be the same angle when they're like that and for number four you can see it's a 90° angle so you subtract 90 - 39 so that you can get the answer that way

it would be 0.18 because when the other choices are converted they equal those two numbers.   hope this !
