Answer:
11. I disagree with Marisol because 23 is the only exterior angle for remote interior angles 21 and 22.
12. w = 75 not 124
Explanation:
12. the sum of a triangle is 180, so to find "w" the student should've added to find x 44+31= 75. 75+56 = 131. 180-131= 49. x = 49. a straight line is also 180 degrees. to find "w" they should've added 56+49 = 105. 180- 105 = 75.
