You haven't given us the vector, and there an infinite number of planes through the two points.
ab^2 = be^2 + ae^2 pythagorean theorem e is the point below b
6.5^2 = 6^2 + ae^2
42.25 = 36 +ae^2
6.25 = ae^2
2.5 = ae
23 = ae +ef +fd f is the point below c
23 = 2.5 + 9 +fd
fd = 11.5
tan D = opp/adj
tan D= cf /fd
tan D = 6/11.5
D = tan^-1 (6/11.5)
D =27.5528
D = 27.6 degrees
Answer:
(x+2)^2 + (x+4)^2 = 169

Hope you can still understand the way I solved the question
If you have any questions about the way I solved it, don't hesitate to ask ;)
They make 8 together it would be 8 for the answer ^_^
