By the isosceles triangle theorem the two angles opposite the equal sides are themselves equal while if the third side is different then the third angle is different.
Answer:

And replacing we got:

And we can find the angle with the inverse cosine function and we got:

Step-by-step explanation:
for this case we can use the following identity:

We can begin finding the norm for each vector and we got:


Now we can find the dot product and we got:

And replacing we got:

And we can find the angle with the inverse cosine function and we got:

The midpoint would be A: (6,3) :)
