The perimeter of the polygon that circumscribes the circle below is? where \mathrm{A}\mathrm{D}=3.7AD=3.7 inches, \mathrm{C}\mathrm{D}=3.6CD=3.6 inches, and \mathrm{B}\mathrm{C}=3.4BC=3.4 inches ​ .

answer: c

step-by-step explanation: because you don't have to draw a point of intersection. couldyou give me brainliest?

u

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

i think the answer is c sorry if it's wrong
