I need help with this problem please!!Hi...I have a problem that really needs to be solved for my study for the exam please.(it is grade 11 problem.) #2 20060122 04:24:11
Re: I need help with this problem please!!I am a little lost. If everything you typed in a) is what you wished type then there is only one triangle possible. Unless there is an equal sign somewhere that shouldn't be there; #3 20060122 05:21:25
Re: I need help with this problem please!!There is a second possible triangle. Why did the vector cross the road? It wanted to be normal. #4 20060122 06:21:17
Re: I need help with this problem please!!Good catch Mathsyperson, I should not rely so heavily on the law of sines. Perhaps an expansion of the law of cosines would be more appropriate? I am wondering if the radical sign would produce two simultaneous solutions like we needed here. #5 20060122 07:07:34
Re: I need help with this problem please!!The law of cosines would give this: Why did the vector cross the road? It wanted to be normal. #7 20060122 08:06:34
Re: I need help with this problem please!!Oh, of course. Sorry, it's just that I don't hear 'radical' being used to mean square root very often, so I forgot about that definition temporarily. Why did the vector cross the road? It wanted to be normal. #10 20060122 10:58:12
Re: I need help with this problem please!!...or 0. Why did the vector cross the road? It wanted to be normal.
