(number of sides) - (2) times (180) = sum of interior angle measurements so for a triangle it is 3-2 which is 1 times 180 = 180, so the answer is 180 degrees

-3 + 4 + (-2) = 1 + (-2) = 1 - 2 = -1.

A sum of 4 is more likely. Out of the 36 possible outcomes with a pair of 6-sided dice, only one will have a sum of 2 {1-1}. Three of the possibilities sum to 4. {1-3, 2-2, 3-1}
