  • 180 = (3x-6)+(4x+25)
    180 = 3x+4x-6+25
    180 = 7x+19
    180-19 = 7x
    161 = 7x
    x = 161:7
    x = 23°

    AOC = (3x-6)
    AOC = (3.23-6)
    AOC = (69-6)
    AOC = 63°

  • 3x - 6 + 4x + 25 = 180
    7x + 19 = 180
    7x = 180 - 19
    7x = 161
    x = 23 

    sudut AOC = 3x - 6 = 3 * 23 - 6 = 69-6 = 63 (B)
