All right, in this one it says, why can the law of signs not be used to solve a triangle if we're only given links of three sides of a triangle? so if you go to the formula for law of signs, that's a over the sign of a equals b over the sign of b equals c over the sign of c.
00:24
Right so if we're given say links of three sides of a triangle so say oh the triangle is like three four and seven right so if you had you know this is a this is b this is c so if you had little a b four over the sign of a equals b.
00:58
Which is three over the sign of b.
01:02
Cross multiply, you know, if you cross multiply, you get three sign a equals four sign b.
01:14
And then, you know, there's, you can't, you know, you have two variables and you only have one equation.
01:23
And so it breaks down.
01:25
And if you look and see, you'll get the same kind of result...
