Answer:
perpendicular
Step-by-step explanation:
When 2 lines intersect at any point, not just in the middle of each (that has nothing to do with it), and they meet to form right angles, the lines are perpendicular to one another and their slopes are opposite reciprocals.
Sum of all interior angles in a triangle = 180
let missing angle = x
x + 144 + 13 = 180
x + 157 = 180
x = 23
answer
23 degrees

The mystery complex number is (5 - i) .
(3 + 2i) x (5 - i) = (17 + 7i)
FOIL it out and you'll see it.
