Sine 35/50???

$${\frac{{\mathtt{35}}}{{\mathtt{50}}}} = {\frac{{\mathtt{7}}}{{\mathtt{10}}}} = {\mathtt{0.7}}$$

$$\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{sin}}{\left({\mathtt{0.7}}^\circ\right)} = {\mathtt{0.012\: \!217\: \!000\: \!835}}$$

$$\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{sin}}{\left({\frac{{\mathtt{35}}}{{\mathtt{50}}}}\right)} = {\mathtt{0.012\: \!217\: \!000\: \!835}}$$

$$\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{sin}}^{\!\!\mathtt{-1}}{\left({\mathtt{0.7}}\right)} = {\mathtt{44.427\: \!004\: \!000\: \!806^{\circ}}}$$
