Answer:
HYPERBOLA
Step-by-step explanation:
We have the statement,
'The set of all points in a plane for which the difference between the distances of a given point to two fixed foci equals a certain constant'.
We know that,
Hyperbola is the set of points such that for point P anywhere on the curve, the absolute distance to the two fixed points is a constant.
i.e. From the figure, we see that, the difference of the distance of P from
and
is equal to constant 2a.
Thus, the term representing the given statement is HYPERBOLA.

Answer:
Due to lack of details, I can come up with several possible answers
if 2 is opposite from ∠3, then ∠2 = 58°
if 2 is opposite from ∠1, then ∠2 = 122°
if 4 is opposite from ∠3, then ∠4 = 58°
if 4 is opposite from ∠1, then ∠4 = 122°
2x-9y and 11x + 3y - 12y - 9x
