We have to prove that the tangent is an odd function.
If the tangent is an odd function, the following condition should be satisfied:

From the figure we can see that the tangent can be expressed as:
We can start then from tan(t) and will try to arrive to -tan(-t):

We have arrived to the condition for odd functions, so we have just proved that the tangent function is an odd function.
Answer:
If M is midpoint of AB, then
AM=MB
4x-5= 2x+11
2x=16
x=8
AM= 4x-5
=4(8)-5
=32-5
=27
BM=2x+11
=2(8)+11
=16+11
=27
Hope it helps:-)
