Answer: From the figure attached,
Point X is the midpoint of line AC.
Since coordinates of the midpoint of the segment joining endpoints and is given by,
Therefore, coordinates of the point X will be, = (a, a)
From triangle AXB,
Length of AB = 2a
Length of AX =
Length of BX =
=
Length of AX = BX =
Therefore, triangle AXB is an isosceles triangle.
Step-by-step explanation:
So for that it will be 382+618 is equal to or better than 1000
I think so
(a) We want to find a scalar function 
such that 
. This means
Looking at the first equation, integrating both sides with respect to 
gives
Differentiating both sides of this with respect to 
gives
Then the potential function is
(b) By the FTCoLI, we have
