Q23
The sum of included angles of closed traverse ABCDEFGA is . . . . . . . .
A.
1080°
AnswerB.
900°
C.
1260°
D.
720°
Answer: Option A
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°.
