perbandingan segitiga = 7 : 8 : 9
jumlh sudut segitiga = 180 derajat
faktor pengali x
maka :
180 = sudut (1+2+3)
180 = 7x + 8x + 9x
180 = 24x
x = 180/24
x = 7,5 derajat
a. besar tiap sudut :
K = 7 X 7,5 = 52,5 derajat
L = 8 x 7 = 60 derajat
M = 9 x 7,5 = 67,5 derajat
b. jenis segitiga = segitiga sembarang atau segitiga lancip
