Question

Jika pada segitiga ABC diketahui tanA=2 dan TanB=3 maka tentukan SinC

Answer 1

Answer:

sin C = sin 45° = 0.707

Step-by-step explanation:

tan A   = 2      therefore   A = $tan^{-1} 2$  =   63.43°

tan B  = 3        therefore   B = $tan^{-1}$3 =   71.57°

therefore C  = 180° - 63.43° - 71.57° = 45°

therefore sin C = sin 45° = 0.707
