Master Determine if there is one, two or no triangles for SSA ambiguous case
Timestamps: 0:00 Intro 0:55 Example #1 (one triangle) 4:30 Example #2 (no triangle) 5:05 Example #3 (two triangles) Corrections: 3:58 I made a mistake, I replaced the side b=15 to the angle A. It should have been h = (15)(sin40); (h = 9.64)
