Besar sudut boc Sudut aoc: 5x-3 Sudut boc: x+15

AOC + BOC = 180
5x - 3 + x + 15 = 180
6x = 180 - 12
6x = 168
x = 168/6
x = 28

BOC = x + 15
BOC = 28 + 15
BOC = 43

AOC + BOC = 180
5x - 3 + x + 15 = 180
6x + 12 = 180
6x = 180 - 12
6x = 168
x = 168/6
x = 28

besar sudut = AOC = 5x - 3 = 5 (28) - 3 = 137°
besar sudut = BOC = x + 15 = 28 + 15 = 43°

maaf klo salah...
