tolong dijawab yg nomor 2!

Matematika = 90°
IPS = 170°
IPA = 45°
PKN = 360 - 170 - 90 - 45 = 55°

Matematika = 90/360 × 72 = 18
IPS = 170/360 × 72 = 34
IPA = 45/360 × 72 = 9
PKN = 55/360 × 72 = 11

Persentase
Matematika = 18/72 × 100 = 25%
IPS = 34/72 × 100 = 47.2%
IPA = 9/72 × 100 = 12,5%
PKN = 11/72 × 100 = 15,28 %
