kak tlong jawab pakek cara y.. plisss besok mau d kumpulin

Seni rupa = 72⁰
Matematika = 108⁰
maka,

x/mtk = 8/sp
x/108 = 8/72
x = 108×8/72
x = 12

jadi,yg gemar mtk ada 12 orang

Jawaban = A. 12

ket :
°sp = Seni Rupa
°mtk = Matematika
°x = yg gemar matematika

seni rupa = 72° = 72/360 =0,2 = 20  % =  8 orang

matematika = 108° = 108/360 = 0,3 = 30 %
                    = 30/20 x 8
                     =3/2 x 8
                     = 3 x 4
                      = 12 orang

jawab.A
