Ray BD bisects ∠ABC so that m∠DBC = x + 8 and

m∠ABD = 2x − 15. What is x?

Ray BD bisects ∠ABC
That means the two angles formed are congruent.
That means their measures are equal. So,
x+8 = 2x-15
Now just find x.
"bisect" means to cut into two equal parts, so

2x-15 = x+8

just solve this trivial equation for x
since everyone else won't answer it, I will. x = 13
thank. you somesh the answer was 13
i got 23?
