Answer 1

Check the picture below.

`\textit{Law of Sines} \\\\ \cfrac{a}{\sin(\measuredangle A)}=\cfrac{b}{\sin(\measuredangle B)}=\cfrac{c}{\sin(\measuredangle C)} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{m}{\sin(113^o)}=\cfrac{7.5}{\sin(57^o)}\implies m\sin(57^o)=7.5\sin(113^o) \\\\\\ m=\cfrac{7.5\sin(113^o)}{\sin(57^o)}\implies m\approx 8.2`

Make sure your calculator is in Degree mode.
