Question

Дано точку C(1;3;2) - середина відрізка AB.Знайдіть точку B (x;y;z), якщо точка A (2;4;-1).​

Answer 1

для нахождения координат искомой точки от удвоенных координат точки C(1;3;2) отнимем координаты точки А.

х=2*1-2=0

у=2*3-4=2

z=2*2-(-1)=4+1=5

Ответ В(0;2;5)

Answer 2

Finding Point B given Point C and Point A

To find the coordinates of point B, we need to consider that point C is the midpoint of the line segment AB.

Let's denote the coordinates of point B as (x, y, z).

Given that point C is the midpoint of the line segment AB, we can use the midpoint formula to find the coordinates of point B.

The midpoint formula states that for a line segment with endpoints (x1, y1, z1) and (x2, y2, z2), the coordinates of the midpoint (x, y, z) are given by:

x = (x1 + x2) / 2 y = (y1 + y2) / 2 z = (z1 + z2) / 2

In this case, point A has coordinates (2, 4, -1) and point C has
