The coordinates of points A and B are A(4.-2) and B(12, 10). What are the coordinates of the point that is of the way from A to B?
O A (1, -0.5)
B. (6, 1)
O
C. (10,7)
D. (3, 2.5)

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

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
