4x + 5x + 6x +10 - 30 - 40 = 180
15x -60 = 180
15x = 180 + 60
x = 240 / 15
= 16
A (4x+10)
= 4. 16 + 10
= 64 + 10
= 74
B (5x-30)
= 5. 16 - 30
= 80 - 30
= 50
C (6x-40)
= 6. 16 - 40
= 96 - 40
= 56
jadi yg terpanjang A
15x - 60 = 180
15x = 180 + 60
15x = 240
x = 16
A = 4x + 10 = 4 ( 16 ) + 10
= 64 + 10
= 74°
B = 5x - 30° = 5 ( 16 ) - 30°
= 80 - 30
= 50°
C = 6x - 40°
= 6(16) - 40
= 96 - 40
= 56°
jadi yang terpanjang adalah sudut A
