Question

Sejam os pontos A(2,5) B(10,-1) C(9,-2), determine o ponto E(x,10) da mediatriz de lado AB do triangulo ABC

Answer 1

Ex= (xa+xb)/2
Ex=(2+10)/2
Ex=12/2
Ex=6

Ey= (ya+yb)/2
Ey= (5+(-1))/2
Ey=4/2
Ey=2

(dcm)^2= (xm-xc)^2+(ym-yc)^2
(dcm)^2= (6-9)^2+(2-(-2))^2
(dcm)^2= (-3)^2+(4)^2
(dcm)^2= 9+16
(dcm)^2= 25
dcm= $\sqrt{25}$
dcm=5
