Answer:

23°

Explanation:

There is not enough information given in this diagram to provide values for the marked angles. In order to solve the problem, we must assume some relation between those angles.

If they are equal, then ...

9x -22 = 6x -7

3x = 15 . . . . . . . . . . add 22-6x to both sides

x = 5 . . . . . . . . divide both sides by 3

m∠ABD = (9x -22)° = (9·5 -22)° = 23°
