Sorry, I'm apparently oblivious, but what is magnetic bearing, because when I google it I just come up with magnetic ball bearings.

1. How many sections are in one PLSS township?
2. The bearing S24W translates to what azimuth?

Your second answer is correct but since when is there more than 36 sections in one township?

Oh sorry I accidentally multiplied 36 by 36 because I guess I mistakenly thought that I didn't count sections...:oops:

New Question
Billy lives in section 25. In the SW1/4/NW1/4, there is a school. Billy lives in the NE1/4/SE1/4. The Post Office is in the SW1/4/SW1/4. If Billy wants to go to school from home, then pick up mail from the post office, then head back home again, in exact measurements calculate the distance traveled by Billy that day. (In other words find the perimeter of the triangle made by the School, the Post Office, and Billy's home)

About 2.36 miles?

That's incorrect. Also remember to use exact answers.
ALSO
Each location is in the center of the 1/16th.

2nd try
((.125)˄1/2+ (5/16)˄1/2+(13/16)˄1/2) miles or about 1.81 miles. The first time I went from school to home, to post office, then back home...

Yeah I'm probably screwing up somewhere with the pythagorean theroem...

Okay, so first we draw a diagram:
Here
_ _ _ _ _ _ _ _ _ _ _ _ _
|
|_ _ _|_ _ _|_ _ _ | _ _ _ |
| S
|_ _._|_ _ _|_ _ _ | _ _ _ |
| ...........................H
|_ _,_|_ _ _|_ _ _ | _ _ _ |
| P
|_ _ _|_ _ _|_ _ _ | _ _ _ |
(S=school, P=post, H-house)
Look where I put the bolded dot. This makes it so that from H to the dot, there is 3/4 of a mile, and from S to the dot, there is 1/4 of a mile, since a section is 1 square mile. Using the Pythagorean theorem we get (3/4)^2 + (1/4)^2 = x^2, and we get x to be /4. Multiply this by 2 to account for both legs of the isosceles triangle. Finally, add 1/2 to account for the base, and we get our answer of
this.
or around 2.08 miles.


hippo9, your turn.

1. What does an x symbolize on a topographic map?
2. The longitude of the western neat line of Quadrangle A is 30 degrees west. What is the longitude of the western neat line of the quadrangle directly to the southwest of Quadrangle A?

The first is right, however the second one is wrong...
