Answer:

3.5

Step-by-step explanation:

Remark

Angle bisectors divide the base line that the bisector is drawn to in the same ratio as the legs making up the bisected angle.

Equation

AD/AC = BD/BC

Givens

  • BC = 6
  • AC = 5
  • BD = 4.2
  • Find AD (x)

Solution

  • x/5 = 4.2/6             Cross multiply
  • 6 * x = 5 * 4.2         Combine the right
  • 6x = 21                    Divide both sides by 6
  • x = 21 / 6
  • x = 3.5                     Answer
