  • nomer 7

    AOC = 2×ABC
    = 2×41°
    = 82°

    AOD = 180° - AOC
    = 180° - 82°
    = 98°

  • 7.
    sudut ABc = 1/2 AOD
    AOD = 2 x ABC = 2 x 41 = 82

    AOD + ABC = 180
    AOD = 180 - 82
    AOD = 98°

    8. OBC = OCB = 52
    BOC+OBC+OCB = 180
    BOC = 180 - 52 -52
    BOC = 76

    BAC = 1/2 BOC
    BAC = 1/2 x 76 
    BAC = 38°
