Find the length of CD. Place point G at (4,-4), and draw CG and GD
. Now you have right ΔCGD with CD
as the hypotenuse. Find GD and CG using coordinates. Then use the Pythagorean Theorem to find CD. Show your work.

Respuesta :

Answer:

GD = |4 − 1| = 3

CG = |0− (−4)| = 4

Using the Pythagorean Theorem to find CD:

CD2  =  GD2 + CG2

CD2  =  32 + 42

CD2   =  9 + 16

CD  =  √25

CD  =  5

Answer:

CG = |0− (−4)| = 4

GD = |4 − 1| = 3

Distance Formula: d = √(x2-x1)^2 + (y2-y1)^2 

CD = √(x2-x1)^2 + (y2-y1)^2 

C = (4,0)

D = (1,-4)

CD = √(1-4)^2 + (-4-0)^2 

CD = √(-3)^2 + (-4)^2 

CD = √9 + 16

CD = √25

CD = 5
