Answer:
They should walk on a bearing of 59.4 degrees
Step-by-step explanation:
Given
![South = 4.2km](https://tex.z-dn.net/?f=South%20%3D%204.2km)
![West = 7.1km](https://tex.z-dn.net/?f=West%20%3D%207.1km)
Required
The bearing back to the base
The given question is illustrated with the attached image.
To do this, we simply calculate the measure of angle a using:
![\tan(a) = \frac{Opposite}{Adjacent}](https://tex.z-dn.net/?f=%5Ctan%28a%29%20%3D%20%5Cfrac%7BOpposite%7D%7BAdjacent%7D)
![\tan(a) = \frac{7.1}{4,2}](https://tex.z-dn.net/?f=%5Ctan%28a%29%20%3D%20%5Cfrac%7B7.1%7D%7B4%2C2%7D)
![\tan(a) = 1.6905](https://tex.z-dn.net/?f=%5Ctan%28a%29%20%3D%201.6905)
Take arctan of both sides
![a = \tan^{-1}(1.6905)](https://tex.z-dn.net/?f=a%20%3D%20%5Ctan%5E%7B-1%7D%281.6905%29)
![a = 59.4^o](https://tex.z-dn.net/?f=a%20%3D%2059.4%5Eo)
Answer:
Step-by-step explanation:
6x6=30 4x4=16 6x4=24
30+16+24= 70 inches square

Answer:
x = - 109/59
y = - 11/59
Step-by-step explanation:
2x+7y=-5
5y-7x=12
by elimination we get
x = - 109/59
y = - 11/59
Answer:
See below.
Step-by-step explanation:
Sides: 15, 36, 41
<u><em>True:</em></u><em> </em>15 + 36 greater-than 41, so the side lengths will form a triangle.
<u><em>True:</em></u> 15 squared + 36 squared = 1,521
<u><em>True:</em></u> 41 squared = 1,681
<u><em>True:</em></u> Since a squared + b squared not-equals c squared, it will not be a right triangle.
