Arectangle has vertices at these corrdinates (1, 2), (3, 2), (1, -8)
what are the coordinates of the fourth vertex of the rectangle

(3,-8)

Step-by-step explanation:

Graph the points on the coordinate plane. Since a rectangle has equal sides with 90 degree angles, the last point will be below (3,2) at the same level as (1,-8). This point is (3,-8).

the answer is 5/14.

hope this .
