  1. (correct answer)
  5. Not enough information to solve

Explanation: The key to solving this problem lies in the geometric fact that a triangle possesses a total of between its interior angles. Therefore, one can calculate the measure of and then find the measure of its supplementary angle, . and are supplementary, meaning they form a line with a measure of . One could also solve this problem with the knowledge that the sum of the exterior angle of a triangle is equal to the sum of the two interior angles opposite of it.
