the other 3 angles are 150 degrees, 30 degrees, and 150 degrees.
the two lines form 4 angles, the opposite two of which are congruent (vertical angles) and the two adjacent angles are supplementary (form 180 degrees)

They have to add up to 360. The angle opposite of 30 is also 30, and the supplements are 150 because 150+30=180. 180 x 2=360.
I feel like I didn't explain that very well, but I hope it helped a little...

the opposite angle is obviously also 30, and the other two are 180-30=150,
30, 150, 150

the one across from the 30 is also 30 then subtract 60 from 180 and then divide it by 2. \
