Best ResponseYou've already chosen the best response.0they are talking about the ambiguous angles in sin case. Your triangle should look like this : dw:1435482187660:dw you need to use the formula for the triangle, so since the formula is: \[Area= \frac{ 1 }{ 2 }ab*sinx\] \[31 = \frac{ 1 }{ 2 } *13*9 *\sin x\] \[sinx = \frac{ 31 }{ \frac{ 1 }{ 2 }*9*13 } = 0.5299\] \[x=\sin ^{1}(0.5299) = 31.99°\] so since this a ambiguous case the other angle will be 180  31.99 = 148°
