Evan walks his dog 4 times around the perimeter of a
park, for a total distance of 2.8 kilometers. How many
kilometers does he walk each time around?
A) 0.07
B) 0.12
C) 0.7
D) 1.2
Please give me the steps to solve this at least if you don’t know that answer, thank you :)

i think it would be 42cm

236 cm 16 time 12 = 192

6 times 7 = 42

192+42

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
