polygon abcde is reflected to produce polygon abcde. what is the equation for the line of reflection?
ay=0
b. x0
oc, x=2
dy1

i am thinking c. sorry if im wrong .

step-by-step explanation:

its a straight line parallel to the time axis

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

150

(sorry i'm not typing it again just read the other two explanation sections i just typed it'll be the same.)
