probs my last question for tday someone HELP and ty

Answer:
[tex]53.6^{o}[/tex]
Step-by-step explanation:
in order to find the angle, you rearrange the cosine rule from the last answer to find cosθ:
[tex]cosA=\frac{b^{2} + c^{2} - a^{2} }{2bc}[/tex]
Substitute the values:
[tex]cos^{-1} (\frac{30^{2}+32^{2} -28^{2} }{2*30*32})=53.57642636[/tex]
