Question

What is the length of an with endpoints a 3,2 and b 8,14

Answer 1

`\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{3}~,~\stackrel{y_1}{2})\qquad (\stackrel{x_2}{8}~,~\stackrel{y_2}{14})\qquad \qquad d = √(( x_2- x_1)^2 + ( y_2- y_1)^2) \\\\\\ d=√((8-3)^2+(14-2)^2)\implies d=√(5^2+12^2) \\\\\\ d=√(169)\implies d=13`
