Question

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.
