Question

Tentukan besar masing masing sudut segitiga jika perbandingan sudut-sudutnya 2:5:8!

Answer 1

180 = 2a + 5a + 8a
180 = 15a
    a = 180 : 15
    a = 12°

Perbandingan 2 :
2a = 2 × 12° = 24°

Perbandingan 5 :
5a = 5 × 12 = 60°

Perbandingan 8 :
8a = 8 × 12 = 96°

Answer 2

dik = jumlah perbandingan = 2+5+8 = 15
sol=jumlah sudut segitiga = 180 derajat
= dit/dik x sol=2/15 x 180 = 24 derajat
=dit/dik x sol = 5/15 x 180 = 60 derajat
= dit/dik x sol=8/15 x 180 = 96 derajat
