Question

in a triangle abc the internal bisector of angle a meets bc at d and angle bisector be is on ac if ab 5cm and be 7 cm find area of triangle abc ​

Answer 1

Step-by-step explanation:

Hey there,

In ∆ABC ,if AD is angle bisector of angle A,

Then ,AB:AC=BD:DC (by internal angle bisector theorem)

Then ,BD=5cm ,BC=7:5 cm

=>DC=7.5-5=2.5

AB:AC=BD:DC=5:2.5=2:1

Hope it helps
