1.

\(\begin{array}{|rcll|} \hline \cos(\varphi_1) &=& 0.4444 \\ \varphi_1 &=& \arccos(0.4444) \\ \varphi_1 &=& 63.6150426705^{\circ}\\ \varphi_1 &=& 63^{\circ}\ 36^{'}\ 54.15^{''}\\ \hline \end{array}\)

 

2.

\(\begin{array}{|rcll|} \hline \cos(\varphi_2) &=& 0.4444 \\ \varphi_2 &=& -\arccos(0.4444) + 360^{\circ} \\ \varphi_2 &=& -63.6150426705^{\circ} + 360^{\circ} \\ \varphi_2 &=& 296.384957330^{\circ} \\ \varphi_2 &=& 296^{\circ}\ 23^{'}\ 5.85^{''}\\ \hline \end{array}\)
