Answer:
73
Step-by-step explanation:
When you have a line intersecting another line, the angles produced by the intersection will be equal to 180.
This means that (-39 + x) + 146 = 180. Solve for x.
(-39 + x) + 146 = 180
-39 + x = 34
x = 73

A(n) = 2 + 9(n - 1) = 2 + 9n - 9
A(n + 1) = 2 + 9(n + 1 - 1) = 2 + 9n = (2 + 9n - 9) + 9 = A(n) + 9
Therefore, the recursive formular is A(n) = A(n - 1) + 9
