Answer: 1) C 2) D 3) 26 4) A 5) 68 6) Triangle MNL
Explanation: 1) C does not equal to 180. If you add up all the numbers it adds up to 169. Any triangle; interior adds up to 180. 2) When you minus 180 - 29.1 - 80 ; it equals to 70.9. 3) 180 - 32 - 122 = 26. You could also add 32 + 122; getting 154. Then 180 - 154. 4) We see a square box, meaning it's a right triangle. 180 - 90 - 42.7 = 47.3. 5) You can draw a picture to help you and see it visualize it. But it's the same process : 180 - 97 - 15 = 68 6) The whole triangle was 180. Equaling the whole as 108 was wrong.
