Rectangle ABCD is graphed in the coordinate plane. The following are the vertices of the rectangle: A(5,5), B(7,5), C(7,-1), and D(5, -1).
Given these coordinates, what is the length of side BC of this rectangle?
units

The length of the side BC is 6 units

Step-by-step explanation:

Distance Between two Points in the Plane

Given two points A(x1,y1) and B(x2,y2), the distance between them is:

We need to calculate the distance between B(7,5) and C(7,-1):

d=6

The length of the side BC is 6 units

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.
