  1. Convert 45°30'36" to decimal degrees.

    Answer: 45.5100°

    30' = 0.50° and 36" = 0.01°, so the total is 45.51°.

  2. What is the azimuth (from north) of a line with bearing S 35°20' E?

    Answer: 144°40'

    For the SE quadrant, azimuth = 180° − bearing = 144°40'.

  3. What is the sum of the interior angles of a closed six-sided traverse?

    Answer: 720°

    (n − 2) × 180° = 4 × 180° = 720°.

  4. The U.S. survey foot is defined as:

    Answer: 1200/3937 m

    The U.S. survey foot equals 1200/3937 m; the international foot is exactly 0.3048 m.

  5. How many square feet are in one acre?

    Answer: 43,560

    One acre equals 43,560 sq ft, which is also 10 square chains.

  6. How many gradians (gons) make up a full circle?

    Answer: 400

    A full circle is 400 gon, so a right angle is 100 gon.

  7. What is the back azimuth of a line with azimuth 287°15'?

    Answer: 107°15'

    287°15' − 180° = 107°15'.
