Answer:
![C \approx 91.732^{\circ}](https://tex.z-dn.net/?f=C%20%5Capprox%2091.732%5E%7B%5Ccirc%7D)
Step-by-step explanation:
(This exercise is presented in Spanish and for that reason explanation will be held in such language)
El lado restante se determina por la Ley del Coseno:
![a = \sqrt{b^{2}+c^{2}-2\cdot b\cdot c \cdot \cos A}](https://tex.z-dn.net/?f=a%20%3D%20%5Csqrt%7Bb%5E%7B2%7D%2Bc%5E%7B2%7D-2%5Ccdot%20b%5Ccdot%20c%20%5Ccdot%20%5Ccos%20A%7D)
![a = \sqrt{5.79^{2}+10.4^{2}-2\cdot (5.79)\cdot (10.4)\cdot \cos 54.46^{\circ}}](https://tex.z-dn.net/?f=a%20%3D%20%5Csqrt%7B5.79%5E%7B2%7D%2B10.4%5E%7B2%7D-2%5Ccdot%20%285.79%29%5Ccdot%20%2810.4%29%5Ccdot%20%5Ccos%2054.46%5E%7B%5Ccirc%7D%7D)
![a \approx 8.466](https://tex.z-dn.net/?f=a%20%5Capprox%208.466)
Finalmente, el angulo C se halla por medio de la misma ley:
![\cos C = - \frac{c^{2}-a^{2}-b^{2}}{2\cdot a \cdot b}](https://tex.z-dn.net/?f=%5Ccos%20C%20%3D%20-%20%5Cfrac%7Bc%5E%7B2%7D-a%5E%7B2%7D-b%5E%7B2%7D%7D%7B2%5Ccdot%20a%20%5Ccdot%20b%7D)
![\cos C = -\frac{10.4^{2}-8.466^{2}-5.79^{2}}{2\cdot (8.466)\cdot (5.79)}](https://tex.z-dn.net/?f=%5Ccos%20C%20%3D%20-%5Cfrac%7B10.4%5E%7B2%7D-8.466%5E%7B2%7D-5.79%5E%7B2%7D%7D%7B2%5Ccdot%20%288.466%29%5Ccdot%20%285.79%29%7D)
![\cos C = -0.030](https://tex.z-dn.net/?f=%5Ccos%20C%20%3D%20-0.030)
![C \approx 91.732^{\circ}](https://tex.z-dn.net/?f=C%20%5Capprox%2091.732%5E%7B%5Ccirc%7D)
