tolong saya ini penting!!!

SMP = 108°
SD = 72°
SMA = 162°
SMK = 360° - (108+72+162)
SMK = 360° - 342°
SMK = 18°

smk = presentase smk / presentase seluruh siswa x jumlah seluruh siswa
smk = 18°/100° x 200 = 36 siswa

360° = 108° + 72° + 162° + SMK
360° = 342°+ SMK
SMK = 360°- 342°
SMK = 18°

18× 200 / 360 = 3600/360
=10 siswa
