Answer:
Coordinate A would be (12,3)
Coordinate B would be (12,7)
Coordinate C would be (10,5)
4^2 = 16
16 x 2 = 32
32, Hope this helps!
Answer:
I would say plane XYN
Step-by-step explanation:
slope = rise over run = y/x
A (-1,3) slope = 3/-1 = -3
B (1,2) slope = 2/1 = 2
C (-3,-1) slope = -1/-3 = 1/3
2 lines need to be negative reciprocals in order to be a right triangle
negative reciprocal of -3 is 1/3
so this is a right triangle
