Discuss
Answer & Solution
Answer: Option A
Solution:
The sum of the included angles of a closed traverse can be calculated using the formula:

Sum of included angles = (n - 2) × 180°

where n is the number of sides of the traverse.

For a closed traverse ABCDEFGA, there are 7 sides (n = 7).

Therefore, the sum of the included angles is:

(7 - 2) × 180° = 5 × 180° = 900° + 180° = 1080°.

Thus, Sum of included angles = 1080°.
