Answer:

Step-by-step explanation:

[tex]c^2=a^2+b^2-2ab\cos\angle C\\c^2=10^2+4^2-2\cdot 10\cdot 4\cos\angle{35^o}\\c^2=100+16-80\cdot\cos\angle{35^o}=116-80\cdot\cos\angle{35^o}\approx 50.47\\c\approx 7.1\\\angle A=\arcsin(\frac{a}{c}\sin\angle{C})\approx 126.1^o,\quad\angle B=\arcsin(\frac{b}{c}\sin\angle{C})\approx 18.9^o[/tex]
