Answer 1

1 = 150

2 = 30

4 = 150

5 = 82

6 = 98

8 = 82

Explanation:

Angles that are next to each other are equal to 180, these angles are called adjacent. The angles that are across are equal to each other, they're called vertical angles and they are always congruent (equal).

Example:

< 3 + < 4 = 180

30 + < 4 = 180

- 30 -30

< 4 = 180

you can do the same thing with < 7 as well.
