THANK YOU SO MUCH

it's me again. Is the answer B?

Step-by-step explanation:

(Page 1):

1.) 150°

2.) 25°

3.) 120°

4.) 60°

(Page 2):

1.) 180 - (40 + 30) = 110°

2.) 180 - (33 + 92) = 55°

(Page 3 doesn't show questions all the way)

Step-by-step explanation:

(Page 1):

1.) ∠1 and ∠2 are Straight angles which make up 180° if added up together => 180° - 30° = ∠2

2.) ∠5 and ∠8 are Vertical angles which means they are congruent ,             => if ∠5 = 25 then so will ∠8.

3.) By the opposite side alternate interior angles theorem ∠6 is congruent to ∠3,      

=> if ∠6 = 120, then ∠3 = 120

4.) if there is a set of an exterior angle and an interior angle, they both add up to 180°.

=> 180° - 120° =  ∠4
