you want
SinB=(sin50 degrees) *2/3 ??
I do not understand what this last bit is for "hm put it in degrees sin=0.22"
$${\frac{\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{sin}}{\left({\mathtt{50}}^\circ\right)}{\mathtt{\,\times\,}}{\mathtt{2}}}{{\mathtt{3}}}} = {\mathtt{0.510\: \!696\: \!295\: \!412\: \!666\: \!7}}$$
$$\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{sin}}^{\!\!\mathtt{-1}}{\left({\frac{\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{sin}}{\left({\mathtt{50}}^\circ\right)}{\mathtt{\,\times\,}}{\mathtt{2}}}{{\mathtt{3}}}}\right)} = {\mathtt{30.710\: \!220\: \!766\: \!103^{\circ}}}$$
B=30.71 degrees
$${\mathtt{0.710\: \!220\: \!766\: \!103}}{\mathtt{\,\times\,}}{\mathtt{60}} = {\mathtt{42.613\: \!245\: \!966\: \!18}}$$
$$\left({\mathtt{0.710\: \!220\: \!766\: \!103}}{\mathtt{\,\times\,}}{\mathtt{60}}{\mathtt{\,-\,}}{\mathtt{42}}\right){\mathtt{\,\times\,}}{\mathtt{60}} = {\mathtt{36.794\: \!757\: \!970\: \!8}}$$
B = 30 degrees 42 minutes and 376 seconds to the nearest second.
If you want the minutes and seconds it would be easier to do on your home calculator.
