+118725 do you mean cos(angle)=1/3
find the angle?
If you do then
angle = acos(1/3)
acos is the same as inverse cos
$$\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{cos}}^{\!\!\mathtt{-1}}{\left({\frac{{\mathtt{1}}}{{\mathtt{3}}}}\right)} = {\mathtt{70.528\: \!779\: \!365\: \!509^{\circ}}}$$
