4x + 10 + 5x - 30 + 6x - 40 = 180
4x + 5x + 6x + 10 - 30 - 40 = 180
15x - 60 = 180
15x = 180 + 60
15x = 240
x = 240 / 15
x = 16
besar sudut-sudutnya :
4x + 10 = 4(16) + 10 = 64 + 10 = 74 derajat
5x - 30 = 5(16) - 30 = 80 - 30 = 50 derajat
6x - 40 = 6(16) - 40 = 96 - 40 = 56 derajat
sudut terbesar = A
sisi terpanjang berarti BC
