HELP PLS I NEED TO FIND THE MEASURE FOR 1 2 AND 3 PLS!!!!'

ONLY QUESTION 37!!

Answer 1

∠1=70

∠2=110

∠3=30

Explanation:

Triangle angles added up = 180 degrees. So, ∠1= 180-30-80=70

Straight lines are 180 degrees as well. So ∠2=180-∠1=180-70=110

Solve for ∠3 in the same way as ∠1. ∠3=180-40-∠2=180-40-110=30
