tolong bantuin jawab dong besok mau di kumpul
Jawaban:
gunakan rumus sudut phytagoras
sin = ab /ac
cos = bc/ac
tg = ab/bc
gunakan salah satu
nomer 1
jumlah segitiga adalah 180
sin 30 = ab/ac
sin 30 = 6/ac
1/2 = 6/ac
ac = 12 cm
cos 60 = bc/ac
1/2 = bc/12
bc = 6 cm
nomer 2
sin = ab/ac
sin 45 = ab/8√2
1/2√2 = ab/8√2
ab = (8√2 * √2) /2
ab = (8 x 2 )/2
ab = 8
