How to determine the altitude by using the geometric mean
Learn about the geometric mean of numbers. The geometric mean of n numbers is the nth root of the product of the numbers. To find the geometric mean of n numbers, we first multiply the numbers and then take the nth root of the product.

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)
