(BRAINLIEST) The coordinate grid shows the graph of △XYZ. △XYZ is reflected across the line x = 2 to form △X’Y’Z’. The △X’Y’Z’ is reflected across the line y = -1 to form △X’’Y’’Z’’. What are the coordinates of Z’’?

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong

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
