Answer 1

Answer:

i am not sure that this is u r answer

but to have it

Answer 2

Answer:

Explanation:

Answer:

BD=7.5 cm and DC=4.5 cm

Step-by-step explanation:

Angle bisector theorem:

when the vertical angle of a triangle is bisected, the bisector divides the base into two segments which have the same ratio as the order of other two sides

Let,BD = x

Then, DC=12-x

By angle bisector theorem,

3x=60-5x

3x+5x=60

8x=60

x=7.5

BD=7.5 cm and DC=4.5 cm
