Final answer:

If angles 13 and 14 are corresponding angles, we can set up an equation to find the value of x and then substitute it into the expression for m_2.

Step-by-step explanation:

Given that line a is parallel to line b and that line c is parallel to line d, we can conclude that angles 13 and 14 are corresponding angles. Corresponding angles that are formed by parallel lines are congruent.

Therefore, if m_13 = (12x - 22)° and m_14 = (93-29)°, we can set up the equation:

(12x - 22)° = (93-29)°

Simplifying the equation, we have:

12x - 22 = 64

12x = 86

x = 7.17

To find m_2, we substitute the value of x into the expression for m_2:

m_2 = 12x - 22 = 12(7.17) - 22 = 70°

Therefore, the answer is B. 70°.
