Answer:

  70°

Step-by-step explanation:

Angles 2 and 13 are alternate exterior angles, so are congruent. The value of x can be found by solving the equation that equates the expressions for the measures of these angles. Once x is found, the measure of angle 13 can be determined. The measure of angle 9 is the supplement of angle 13.

So, ...

  m∠2 = m∠13

  8x +14 = 10x -10

  24 = 2x  . . . . . . . .  add 10-2x

  12 = x

  m∠13 = 10x -10 = 10·12 -10 = 110

  m∠9 = 180° -110°

  m∠9 = 70°
