Chapter 2: Q1. (page 55)

Another orienteering party sights on Lily Bay Mountain and the lookout tower and finds the following angles: mountain, 58鈭�west of north; tower,40鈭�east of north. Are they north or south of you?

Short Answer

Expert verified

They are north of you.

Step by step solution

01

Step 1. Define magnetic north

Magnetic north is the direction towards the north magnetic pole, it is point where the Earth's magnetic field goes vertically down.

02

Step 2. Draw the diagram.

On map, draw a line n,40鈭� east of magnetic north as shown in figure.

You are somewhere near this line AB.

Draw a line 鈥�濒鈥� indicating any features near your location such as trail, stream or pond.

Draw a line 鈥�尘鈥�, 58鈭�west of magnetic north as shown in figure.

03

Step 3. State the conclusion.

Your location indicates where these three lines cut.

These three lines might cross at a single point but due to error it will form a triangle, if the triangle is small then it is your true position. It is clear that they are north of your location.
