The verticales of triangle xyz are x(-3,-6),y(21,-6),and z(21,4). what is the perimeter of the triangle

Step-by-step explanation:

The formula of a distance between two points:

X(-3, -6), Y(21, -6). Substitute:

X(-3, -6), Z(21, 4). Substitute:

Y(21, -6), Z(21, 4). Substitute:

The perimeter of the triangle XYZ:

Substitute:

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
