I need some help. ABC = 8x - 10, and I'm supposed to find the measurements of ABD, and DBC.

Assuming BD bisects angle ABC,

ABD and DBC are both (8x-10)/2 = 4x-5

If there is other information you have withheld, now is the time to present it.

Between A and D is 2x + 8. That's everything I have.

in that case, if in fact BD bisects angle ABC, 4x-5 = 2x+8

Now you can solve for x, and then get the angle measures.

Thanks.

To find the measurements of ABD and DBC, we need more information about the diagram or figure you are referring to. ABC, ABD, and DBC may represent angles or sides of a triangle, or some other geometric figure. Could you please provide more context or details about the diagram?
