Answer:

24 =m

Step-by-step explanation:

We can use the angle bisector theorem

AB           AC

--------- = ----------

BD            DC

Substituting in known values

42           35

------ = -----------

m         n

BC = 44  We know that 44 = m+n.  Solving for n  n = 44-m

42           35

------ = -----------

m          44-m

Using cross products

42(44-m) = 35m

Distribute

1848 -42m = 35m

Add 42m to each side

1848 -42m+42m = 35m+42m

1848 = 77m

Divide each side by 77

1848/77 = 77m/77

24 =m
