SpletUse the Law of Sines to get one possible angle A: sin (A)/a=sin (C)/c sin (A)/5.6=sin (31)/3.9 sin (A)=5.6sin (31)/3.9 A=arcsin (5.6sin (31)/3.9)=47.6924 Subtract 31 (C) and this angle … SpletAnd it is the foundation for the ambiguous case of the law of sines. (Remember ambiguous means that something has more than 1 meaning). As you can see, two different angles have the same sine value ! So, if I asked you : What angle measurement has a sine value of $$\frac {1}{2} ? $$ You could say two different things--either $$ 30^{\circ}$$ or ...

Spletsin B a n d h = b sin C Since they are both equal to h c sin B = b sin C Dividing through by sinB and then sinC c sin C = b sin B Repeat the above, this time with the altitude drawn from point B Using a similar method it can be shown that in this case c sin C = a sin A Combining (4) and (5) : a sin A = b sin B = c sin C - Q.E.D Obtuse Triangles SpletThe “Law of Sines” is a generic description of what’s in the formula, but the “Law of Equal Perspectives” explains what it means: All parts of the triangle have a perspective on the … is lyft in rome
