Answer
CD - 27.9
Step-by-step explanation:
Point C = (12, -8) and Point D = (5, 19)
CD means the distance between point C and D
[tex]\begin{gathered} CD\text{ = }\sqrt[]{(x1-x2)^2+(y1-y2)^2} \\ \text{where x1 = 12, y1 = -8, x2 = 5, y2 = 19} \\ CD\text{ = }\sqrt[]{(12-5)^2+(-8-19)^2} \\ CD\text{ = }\sqrt[]{7^2+(-27)^2} \\ CD\text{ = }\sqrt[]{49\text{ + 729}} \\ CD\text{ = }\sqrt[]{778} \\ CD\text{ = 27.9} \end{gathered}[/tex]Hence, CD IS 27.9
