Question 1139932
The sides lengths already given


{{{5.9^2+4.6^2-2*5.9*4.6*cos(gamma)=7.2^2}}},{{{Law_Of_Cosines}}}
{{{-2*5.9*4.6*cos(gamma)=7.2^2-5.9^2-4.6^2}}}

{{{cos(gamma)=(5.9^2+4.6^2-7.2^2)/(2*5.9*4.6)}}}
{{{cos(gamma)=0.07608695652}}}
Use calculator to find {{{gamma}}}, and then you can use Law Of Sines to get either of the next angles.
