The data from a closed traverse survey PQRS (run in the clockwise direction) are given in the table

The closing error for the traverse PQRS (in degrees) is______________

Solution:

{n}=4

(number of sides of closed traverse)

(2 {n}-4) × 90^{∘}=360^{∘}

so, error in included angle

=(88+92+94+89)-360=+3^{∘}
