what is the length of $overline{cd}$?
Answer
Explanation:
Step1: Identify coordinates
The coordinate of point C is 380 and the coordinate of point D is 390.
Step2: Calculate length
The length of a line - segment with endpoints (x_1) and (x_2) is given by (|x_2 - x_1|). Here, (x_1 = 380) and (x_2=390), so the length of (\overline{CD}=390 - 380).
