Use the given scale factor and the side lengths of the scale drawing to determine the side lengths of the real object. Scale factor. 2:1 5 in 10 in 13 in Scale drawing Object A. Side a is 11 inches long, side bis 8 inches long, and side cis 3 inches long. B. Side a is 2.5 inches long, side bis 5 inches long, and side cis 6.5 inches long C. Side a is 15 inches long, side bis 12 inches long, and side cis 7 inches long D. Side a is 26 inches long, side bis 20 inches long, and side cis 10 inches long.​

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

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

answer: 4  

the square root of 16 is 4. it is a very simple mathematic concept. a square root when a number multiplied by itself will result in a number. here, the number 16 comes when 4 is multiplied by 4. hence the square root of 16 is 4. you can always figure out a square root by the inverse operation of squaring.
