A traverse with five sides has interior angles with the following measures: 121deg 45 min: 118 deg 25 min; 87 deg 32 min; 98deg 34min, and 113 deg 54 min. Does the traverse close? If not, determne the error in the traverse.

    We must be looking at some kind of polygon of 5 sides.
    If closed, the sum of the interior angles would be
    180(5-2) = 540°

    I added them up and got 540° 10'
    So the "traverse" is not possible
