$\angle ABD$ and $\angle DBC$ are adjacent angles. If $\angle ABD = 1.5x^{\circ}$,$\angle DBC = 2x^{\circ}$,and $\angle ABC = 70^{\circ}$,then find $x$ and the measures of $\angle ABD$ and $\angle DBC$.
- A$x = 20^{\circ}, \angle ABD = 30^{\circ}, \angle DBC = 40^{\circ}$
- B$x = 15^{\circ}, \angle ABD = 22.5^{\circ}, \angle DBC = 30^{\circ}$
- C$x = 25^{\circ}, \angle ABD = 37.5^{\circ}, \angle DBC = 50^{\circ}$
- D$x = 10^{\circ}, \angle ABD = 15^{\circ}, \angle DBC = 20^{\circ}$
