You can put this solution on YOUR website! this depends on the diagram which is missing, if you had one.
if you didn't then you need to make the following assumptions.
abc = 24 and abd = 20 and the point d is not between the points a and c.
in that case, angle cbd would be equal to 44 degrees.
abc = 24 and abd = 20 and the point d is between the points a and c.
in that case, angle cbd would be equal to 24 - 20 = 4 degrees.
