Answer:
Step-by-step explanation:
[tex]c^{2} = a^{2}+b^{2} - 2abCos \ C[/tex]
v² = u² + t² - 2utCos V
= 2.6²+ 6² - 2*2.6*6 Cos 96
= 6.76 + 36 -(31.2)* (-0.1045)
= 42.76 + 3.26
= 46.02
v = √46.02
v≈ 6.78
2) ΔSTU
u² = s² +t² - 2stCos U
= 15² + 85² -2*15*85*Cos 41
= 225 + 7225 -2550* 0.7547
= 7450 - 1924.485
= 5525.52
u = √5525.52
u = 74.33 cm
