Answer

x = 39

Step-by-step explanation:

The angles with measures (3x - 14) and (2x + 25) are alternate exterior angles because they are on opposites sides of the transversal and in the exterior of lines m and n.

So, to find x, we will use the alternate exterior angles theorem. It says that when m and n are parallel, then alternate exterior angles are congruent, then we can write the following equation

3x - 14 = 2x + 25

Solving for x, we get

3x - 14 + 14 = 2x + 25 + 14

3x = 2x + 39

3x - 2x = 2x + 39 - 2x

x = 39

Therefore, the answer is x = 39
