R S The length of RT is 9 feet, and the length of SU is 12 feet. Which statement best explains how to find the area of the kite? A) Add the areas of triangles SRU and STU. B) Multiply the area of triangle STU, which has a base of 12 feet and a height of 9 feet, by 2. Multiply the area of triangle STU, which has a base of 12 feet and a height of 4.5 feet, by 2. D) Multiply the area of triangle SRU, which has a base of 4.5 feet and a height of 12 feet, by 2. 2​

yeah and the opposite of cheating is studying ( you should try it some time)

step-by-step explanation:

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
