Answer:
4.2 ft
Step-by-step explanation:
Given the equation for the Law of Cosines, we can rewrite the equation to solve for "c" directly:
![c^2=a^2+b^2-2ab(cosC)\\c=\sqrt{a^2+b^2-2ab(cosC)}\\c=\sqrt{7^2+8^2-2(7)(8)(cos32)}\\c=\sqrt{49+64-2(56)(cos32)}\\c=\sqrt{113-112(cos32)}\\c=\sqrt{113-94.98138677}\\c=\sqrt{18.01861323}\\c=4.244833711\\c=4.2](https://tex.z-dn.net/?f=c%5E2%3Da%5E2%2Bb%5E2-2ab%28cosC%29%5C%5Cc%3D%5Csqrt%7Ba%5E2%2Bb%5E2-2ab%28cosC%29%7D%5C%5Cc%3D%5Csqrt%7B7%5E2%2B8%5E2-2%287%29%288%29%28cos32%29%7D%5C%5Cc%3D%5Csqrt%7B49%2B64-2%2856%29%28cos32%29%7D%5C%5Cc%3D%5Csqrt%7B113-112%28cos32%29%7D%5C%5Cc%3D%5Csqrt%7B113-94.98138677%7D%5C%5Cc%3D%5Csqrt%7B18.01861323%7D%5C%5Cc%3D4.244833711%5C%5Cc%3D4.2)
So the length of c is approximately 4.2 ft
