Question

In triangle ABC ,ADis the bisector of angle A meeting BC at D . If AB=3.5cm AC =4.2cm and DC=2.8cm find BD

Answer 1

Step-by-step explanation:

hii friend here is ur answer

we know that bisector means which divides a line into two equal parts

here AC=4.2

AD=3.5

BC=2.8

AD is bisector of BC

Therefore BD=1/2×2.8

=2.8/2

=1.4

Answer 2

Step-by-step explanation:

2.8cm

because AD bisects angle A and meet at Bc

there AD also bisects side CB

so CD =BD

so, BD = 2.8cm
