Find the 3 average angles by computing D and R horiztonal angles.

Compute your 3 average horizontal angles by computing D and R horizontal angles by horizontal circle FS minus horizontal BS then averaging the D and R angles. Convert the average horizontal angles to triangle interior angles if necessary.

Solution

First of all check the correction in zeinth circle value and horizontal corcle value and then calculate the average value of the angle in which the maximum value.
