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
