Question

In triangleABC AD is the bisector of angle A .If AB=10cm,AC=14cm,BC=6cm find x​

Answer 1

Step-by-step explanation:

Let BD = x

Then DC = 12-x

Ratio of AB/AC=BD/DCAB/AC=BD/DC

SO , 10/6=x/(12−x)10/6=x/(12−x)

120−10x=6x120−10x=6x

16x = 120

x = 120/16 = 15/2=7.5cm15/2=7.5cm

BD = 15/215/2

DC = 12−15/2=9/2=4.5cm12−15/2=9/2=4.5cm
