asin=7.6/9.8

I think that you mean

 

asin(7.6/9.8)

 

$$\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{sin}}^{\!\!\mathtt{-1}}{\left({\frac{{\mathtt{7.6}}}{{\mathtt{9.8}}}}\right)} = {\mathtt{50.851\: \!312\: \!357\: \!747^{\circ}}}$$

$${asin}\left( = {\frac{{\mathtt{7.6}}}{{\mathtt{9.8}}}} \Rightarrow {asin}\left( = {\mathtt{0.775\: \!510\: \!204\: \!081\: \!632\: \!7}}$$
