Answer:
64
Explanation:
We know that m<ABC is bisected. Hence, m<ABD = m<DBC.
Using the substitution property of equality, we can conclude that
8x - 14 = 2x + 10
Next, we shall solve for x, which is, and substitute 6 into one of the two equations. The correct answer is 32.
By multiplying 32 by 2, we shall arrive at the final answer, 64.
