Two triangles SSA

We can form two triangles with the given information. Use the Law of Sines to solve the triangles.

A = 59°, a = 13, b = 14

Correct answer:

c1 =  12.2097
c2 =  2.2114

Step-by-step explanation:

A=59  a=13 b=14  a2 = b2+c2 2bc cos(A)  k=cosA=cos59° =0.515038=0.51504  a2=b2+c22 b c k  132=142+c22 14 c 0.51503807491005 c2+14.421c27=0 c214.421c+27=0  p=1;q=14.421;r=27 D=q24pr=14.42124127=99.9671473879 D>0  c1,2=2pq±D=214.42±99.97 c1,2=7.210533±4.999179 c1=12.209711666=12.2097 c2=2.211354432
