1) C 2) 62° 3) 60° 4) 80° it’s super easy once you understand but in a triangle if you add all the inner angles they’ll always be 180. Also to find the outer angle all you have to do is add the two inner angles that don’t touch it like that aren’t near it so in number 2 you would add 43 and 19 to find x. For number three you have to subtract the inner angle from the outer angle to find x. For number 4 it shows you that two angles are equal and you know that the sum of the two angles is the outer angle so you divide 160 by 2 and you’ll get 80. I also attached my notes hopefully they’ll help :)
