Answer 2

Thus, the answer is $3:4$

Step-by-step explanation:

Given;

For a $\bigtriangleup abc$, $ab=3cm$, $ac=4cm$ and $ad$ is the bisector of $\angle a$ which meets $bc$

"Angle Bisector" Theorem:

                                               The "Angle Bisector" Theorem says that an angle bisector of a triangle will divide the opposite side into two segments that are proportional to the other two sides of the triangle.

∴$\frac{bd}{dc} =\frac{ab}{ac}$

⇒$\frac{bd}{dc} =\frac{3}{4}$

∴ $bd:dc=3:4$  

So, the answer is $3:4$
