    Question

    Direction : Among given options only for this figure perpendicular bisector theorem is used.

    Find AB.

    1. 2
    2. 8
    3. 4
    4. 12

    hintHint:

    In this question, if we apply perpendicular bisector theorem we get AB = AC. By applying this equation, we can solve the problem.

    The correct answer is: 12

      Step by step solution:
      AB=AC
      rightwards double arrow4x + 4 = 8x – 4
      rightwards double arrow4x = 8
      rightwards double arrowx = 2
      AB = 4 x 2 + 4 = 12 units
      Hence, option(a) is the correct option.
