Solution: Angles from Directions Set 1

Problem (2)

Compute interior angles for the following loop traverse. Identify and perform a math check.

Partial Computations

At point H

Ang_H = Az_HI - Az_HM

Ang_H = (360°00’00” + 88°30’25”) - (145°00’50” + 180°00’00”)

Ang_H = 123°29’35”

At point J

Ang_J = Az_JK - Az_JI = 293°16’55” - (12°00’50” + 180°00’00”)

Ang_J = 101°16’05”

Remaining computations are left to the reader.
