The resultant of two vectors $\overrightarrow{\mathrm{A}}$ and $\overrightarrow{\mathrm{B}}$ is $\overrightarrow{\mathrm{C}}$. If angle between $\overrightarrow{\mathrm{A}}$ and $\overrightarrow{\mathrm{B}}$ is $\mathrm{\theta }$, then what is the angle between resultant and $\overrightarrow{\mathrm{B}}$
