Triangle ABC was dilated with the origin as the center of dilation to create A'B'C'.

Which rule best represents the dilation that was applied to Triangle ABC to create A'B'C'?

A. (x, y,) (13x, 13y) C. (x, y,) (x - 3, y + 3)

B. (x, y,) (3x, 3y) D. (x, y,) (½ x, ½ y)

the answer is somewhere there guys it really . there im just not gonna answer

step-by-step explanation:

but i'm guessing ur first option tho

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
