We will find the value of m as follows:

*Since we have that the triangles contained are similar (by theorem), then the following is true:


(5)/(3+6+3)=(m)/(6+3)

Now, we solve for m:


(5)/(12)=(m)/(9)\Rightarrow m=(9\cdot5)/(12)\Rightarrow m=(15)/(4)\Rightarrow m=3.75

So, the measure of m is 3.75 units.
