this time, i'll ask about how to get the angle in degrees in a coordinate system.
so here's the question:
The vertices of a quadrilateral are located at A(-1,-2), B(3,-4), C(2,3), and D(-2,2).
Q: Find the angle in degrees between sides BC and CD.

Use the distance formula to find the lengths of BC, and CD and BD.Quote:

my final answer is 84.09 degrees.
tnx for your help.
