Best ResponseYou've already chosen the best response.0another approach after using the cosine rule to get the 3rd side use Hero's formula to find the area knowing the 3 sides

Best ResponseYou've already chosen the best response.0"you can verify it with sine rule now that you have 3 sides" Formula for sine rule? "how would we determine the height? do we know any trig functions that we could employ?" I don't know "another approach after using the cosine rule to get the 3rd side use Hero's formula to find the area knowing the 3 sides " I don't know what I did wrong but I got 177
