Sum of two sides of the triangle should be more than 3d side.
n<20+5,
n<25

Third side should be more than difference of two other sides.
n> 20-15
n>5

So, n should be
5<n<25.

What are the coordinates of the midpoint of the line segment with endpoints 2,5 and 4,-7

Phoenix [80]

<h3>Answer: (3, -1)</h3>

===============================================

Explanation:

The midpoint formula is $(x_m, y_m) = \left(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\right)$

This basically says to add the corresponding coordinates and divide by 2.

The given points (2,5) and (4,-7) have x coordinates of 2 and 4. They add to 2+4 = 6, and then that result cuts in half to 6/2 = 3. The x coordinate of the midpoint is 3.

The y coordinate of the midpoint is y = -1 since adding the y coordinates of the given points leads to 5+(-7) = -2 which cuts in half to -1.

So overall the midpoint is located at (3, -1)
