Solve the missing angles
a=15cm b=18cm c=30cm
so If I use
i get angle A is 42.12 degrees but then B and C don't work out i know I can use the law of sine once I have one angle but I am just asking why doesn't B and C work with the law of cosine?
Its -324+225+900/900 =.81 not 1.11www.louisvuittonend.com
