WebWhen you write and solve the law of sines, you end up with sinC=0.32 or something. You type sin^-1 (0.32) in your calculator and you are given an acute angle. Actually there are two solutions to the equation sinC=0.32. One is acute (your calculator gave it to you) and the other solution is obtuse. WebThe law of sines is expressed as follows: a sin ⁡ ( A) = b sin ⁡ ( B) = c sin ⁡ ( C) \frac {a} {\sin (A)}=\frac {b} {\sin (B)}=\frac {c} {\sin (C)} sin(A)a. . = sin(B)b. . = sin(C)c. . where, a, b, c represent the lengths of the sides of the triangle and A, B, C represent the angles of the triangle.
