∆ABC has the points A(1, 7), B(-2, 2), and C(4, 2) as its vertices. What is the measure of the longest side of ∆ABC

Respuesta :

bcalle
AB = sqrt( (-2-1)^2+(2-7)^2)
AB = sqrt 34

BC = sqrt( (-2-4)^2 +(2-2)^2)
BC = sqrt 36

AC = sqrt( (1-4)^2+(7-2)^2)
AC = sqrt 34

BC is the longest side
Sort 36 = 6
