Answer:
530
Step-by-step explanation:
its really easy just put it together
Answer:
Hence, the azimuth, bearing, and length of the line connecting station Shore to station Rock are
and
feet.
Given :
The shore station point
in feet,
![(X_1,Y_1)=(2058.97, 6980.06)](https://tex.z-dn.net/?f=%28X_1%2CY_1%29%3D%282058.97%2C%206980.06%29)
The Rock station point
in feet
![(X_2,Y_2)=(1408.03,6980.06)](https://tex.z-dn.net/?f=%28X_2%2CY_2%29%3D%281408.03%2C6980.06%29)
From the figure
feet
feet
Length of the line ![L=\sqrt{x^2+y^2}](https://tex.z-dn.net/?f=L%3D%5Csqrt%7Bx%5E2%2By%5E2%7D)
![\Rightarrow L=\sqrt{(650.94)^2+0}=650.94](https://tex.z-dn.net/?f=%5CRightarrow%20L%3D%5Csqrt%7B%28650.94%29%5E2%2B0%7D%3D650.94)
feet
![\tan \theta=\frac{y}{x}=\frac{0}{x}=0](https://tex.z-dn.net/?f=%5Ctan%20%5Ctheta%3D%5Cfrac%7By%7D%7Bx%7D%3D%5Cfrac%7B0%7D%7Bx%7D%3D0)
![\Rightarrow \theta=\tan^{-1}(0)=0](https://tex.z-dn.net/?f=%5CRightarrow%20%5Ctheta%3D%5Ctan%5E%7B-1%7D%280%29%3D0)
Azimuth of line![=270^{\circ}+\theta](https://tex.z-dn.net/?f=%3D270%5E%7B%5Ccirc%7D%2B%5Ctheta)
![=270^{\circ}+0](https://tex.z-dn.net/?f=%3D270%5E%7B%5Ccirc%7D%2B0)
![=270^{\circ}](https://tex.z-dn.net/?f=%3D270%5E%7B%5Ccirc%7D)
Bearing ![=360^{\circ}-\text{Azimuth}](https://tex.z-dn.net/?f=%3D360%5E%7B%5Ccirc%7D-%5Ctext%7BAzimuth%7D)
![=360^{\circ}-270^{\circ}](https://tex.z-dn.net/?f=%3D360%5E%7B%5Ccirc%7D-270%5E%7B%5Ccirc%7D)
![=90^{\circ}](https://tex.z-dn.net/?f=%3D90%5E%7B%5Ccirc%7D)
The second option/letter b
They each got 1/4
1/2 = 50%
50% / 2 = 25%
25%= 1/4
