    Question


    ABCED is a kite, AB = 5x – 12, AC = 3x – 2 , BE = 4x , CE = 7x -15 , DC = 10 units,
    AB, AC, BE, CE, DC are line segment
    Find BE.

    1. 15
    2. 20
    3. 30
    4. 25

    hintHint:

    In a kite, AB = AC and BE = CE always. With the help of these equations, we can solve the problem.

    The correct answer is: 20

      Step by step solution:
      BE = CE
      4x = 7x – 15
      rightwards double arrow7x – 4x = 15
      rightwards double arrow3x = 15
      rightwards double arrowx = 5
      BE = 4x = 4 x 5 = 20 units.
      Hence, option(b) is the correct option.
