From the picture, we can see that
![\sin\theta=\dfrac HB\implies\dfrac{\sin\theta}C=\dfrac H{BC}](https://tex.z-dn.net/?f=%5Csin%5Ctheta%3D%5Cdfrac%20HB%5Cimplies%5Cdfrac%7B%5Csin%5Ctheta%7DC%3D%5Cdfrac%20H%7BBC%7D)
![\sin\beta=\dfrac HC\implies\dfrac{\sin\beta}B=\dfrac H{BC}](https://tex.z-dn.net/?f=%5Csin%5Cbeta%3D%5Cdfrac%20HC%5Cimplies%5Cdfrac%7B%5Csin%5Cbeta%7DB%3D%5Cdfrac%20H%7BBC%7D)
which means
![\dfrac{\sin\theta}C=\dfrac{\sin\beta}B](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Csin%5Ctheta%7DC%3D%5Cdfrac%7B%5Csin%5Cbeta%7DB)
