Answer:

12.4 miles, N84.4°E

Step-by-step explanation:

Split the translation over the components parallel to the direction S>N and W>E, then calculate the sum of both components, and get magnitude and direction of the movement. Here's my calculation, double check them regardless.

For the first hour, it travels 8.5 cos 37.5 north and 8.5 sin 37.5 east. Once the wind changes, it flies 6*1.5 cos (180-52.5) = 9 cos 127.5 "north" ( the actual movement is southbound, which will appear calculating the cosine and getting a negative number) and 6*1.5 sin (180-52.5) = 9 sin 127.5. The complete movement is 1.2 miles N and 12.3 miles E. The total movement is, with the Pythagorean theorem, 12.4 miles total, and the angle it forms with the north direction is the tan^{-1} \frac{12.3}{1.2} = 84.4°.

Alborosie

Answer:

The side length is 9 m

Step-by-step explanation:

The area of a square is given by

A = s^2

81 = s^2

Take the square root of each side

sqrt(81) = sqrt(s^2)

9 =s

The side length is 9 m
