The diagram is missing but I'll assume that the arc BDC is:
![(4k + 159)^{\circ}](https://tex.z-dn.net/?f=%284k%20%2B%20159%29%5E%7B%5Ccirc%7D)
And another arc, let's call it FGH. measures:
![(2k + 153)^{\circ}](https://tex.z-dn.net/?f=%282k%20%2B%20153%29%5E%7B%5Ccirc%7D)
If those arc are equal, then this equation is true:
![(4k + 159)^{\circ}=(2k + 153)^{\circ} \\ \\ (4k + 159)=(2k + 153) \\ \\ \\ Solving \ for \ k: \\ \\ 4k-2k=153-159 \\ \\ 2k=-6 \\ \\ k=-\frac{6}{2} \\ \\ k=-3](https://tex.z-dn.net/?f=%284k%20%2B%20159%29%5E%7B%5Ccirc%7D%3D%282k%20%2B%20153%29%5E%7B%5Ccirc%7D%20%5C%5C%20%5C%5C%20%284k%20%2B%20159%29%3D%282k%20%2B%20153%29%20%5C%5C%20%5C%5C%20%5C%5C%20Solving%20%5C%20for%20%5C%20k%3A%20%5C%5C%20%5C%5C%204k-2k%3D153-159%20%5C%5C%20%5C%5C%202k%3D-6%20%5C%5C%20%5C%5C%20k%3D-%5Cfrac%7B6%7D%7B2%7D%20%5C%5C%20%5C%5C%20k%3D-3)
Substituting k into the first equation:
![\angle BDC=(4(-3)+159)^{\circ} \\ \\ \angle BDC=(-12+159)^{\circ} \\ \\ \boxed{\angle BDC=147^{\circ}}](https://tex.z-dn.net/?f=%5Cangle%20BDC%3D%284%28-3%29%2B159%29%5E%7B%5Ccirc%7D%20%5C%5C%20%5C%5C%20%5Cangle%20BDC%3D%28-12%2B159%29%5E%7B%5Ccirc%7D%20%5C%5C%20%5C%5C%20%5Cboxed%7B%5Cangle%20BDC%3D147%5E%7B%5Ccirc%7D%7D)
