Can someone help me with this problem?
This is the information given
-ABCD is a square the length of the sides is 1
-M is the center of AB.
-The circles have center M and a radius equal to MC
-F is the right intersection between the circle s and line l through A and B
-G is the intersection of line m through --C and D and line n that passes through point F and is perpendicular to l.
a) We insert a coordinate system with origin in the point M and with x axis along l. Find the MA and MC vectors. Find an exact value for cos (angle AMC).
I have found both the vectors, but can not find cos (angle AMC)

If you found the two vectors then you can use the dot product (*) to get the cos (AMC)
