Answer:

Explanation:

$c^(2) = a^(2)+b^(2) - 2abCos \ C$

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
