A. 0,35 rad =...° 0,35 x 180/3,14 = 20,06° B. 0,75 rad=...° 0,75 x 180/3,14 = 42,99 => 43 2.) a. 45° 15' 25" 45° + 15.(1/60)° + 25.(1/3.600)° (162.000/3.600)° + (900/3.600)° + (25/3.600)° (162.925/3.600)°.0,0174 0,79 rad b. 330° 25' 330° 25' = 330° + 25.(1/60)° = (990/3)° + (1/3)° = (991/3)° = (991/3)°.0,0174 = 5,75 rad 3.) 4.) a+60A°+30A°=180A° a=90A° gunakan aturan sinus π\sin(60A°)=a/sin(90A°) π=200/1×√⅔ π=100√3 Tinggi pohon dimisalkan h.nilai h dapat dicari dengan H=π sin(30A°) H=100√3×½ H=50√3m 5.) COS 60° = Sa/Mi = 5/Mi 1/2 = 5/Mi Mi = 2/1 . 5 Mi = 10cm 6.) A. • cos A = b/c =√3 /2 = 1/2 √3 • tan A = a/b = 1/√3 = 1/3 √3 B. - sec A = 1/cesA = 1/ b\c = c/b = 2√3 = 2 √3
