Given the two points (x_1, y_1) and (x_2, y_2), the Distance between them is given by the formula:

color(green)( d = sqrt((x_2-x_1)^2+(y_2-y_1)^2

Here, the coordinates of the points are (5, 8) and (5, 1)

d_(CD) = sqrt((5-5)^2+(1-8)^2

= sqrt((0)^2+(-7)^2

= sqrt(0+49)

= sqrt(49)

= 7 units

The distance from C(5, 8) to D(5, 1) is 7 units.
