3 radian senilai dengan....?? A. 171 derajat 53' 15'' B. 171 derajat 15' 53'' C. 170 derajat 55' 15'' D. 157 derajat 43' 15'' E. 167 derajat 47' 45''

Bab Radian
Matematika SMA Kelas X

1 rad = 1 x 180°/π
1 rad = 180°/π
maka,

3 rad = 3 x 180°/π
3 rad = 540°/π
3 rad = 171,8874°
3 rad = 171° + 0,8874°
3 rad = 171° + (0,8874 x 60')
3 rad = 171° + 53,244'
3 rad = 171° + 53' + 0,244'
3 rad = 171° + 53' + (0,244 x 60")
3 rad = 171° + 53' + 14,64"
3 rad = 171° + 53' + 15"

jawabannya A



# 14,64 ≈ 15
