Given square ERTN, what is the length of NT ?

lesya [120]

Answer:

|NT| = 25

Step-by-step explanation:

The four sides of this square all have the same length. Thus, 5x = 10x - 25, which, in turn, becomes 25 = 5x, giving us x = 5. The length of NT is 5(x), or |NT| = 25.

The midpoint of AB is M(3, 3). If the coordinates of A are (2, -1), what are the

Vika [28.1K]

Step-by-step explanation:

Hey there!!

It's so simple.

While finding the coordinates of any point if the midpoint is there it will be much easier. You must remember the midpoint formulae.

Let's simply work with it.

Here, A (2,-1) and midpoint M(3,3) are given.

Let another coordinate be B(x,y).

By midpoint formulae,

$midpoint(x.y) = \frac{x1 + x2}{2} ,\frac{y1 + y2}{2}$
