There are 180 degrees in any and all triangles.
There is 8 triangles in the Star of David.
All triangles have 3 sides and so two triangles would have a total of 6 sides

Well, it just so happens that I figured this out for whoever was wondering... When n is even, and n+1 is odd (obviously) Sn+1 = Sn + (n+2)(3n+2)/4 When n is odd, and n+1 is even (obviously) Sn+1 = Sn + (n+1)(3n+5)/4 These formulas are for the total triangles in something that looks like this... /\ /_\ /\ /\ /_\ /_\ /\ /\ /\ /_\ /_\ /_\ This triangle has n=3 and has 13 total triangles. The general formula for total triangles is hard to find. And because this question doesn't ask for the general solution for any n, I won't post it. It is really fun to find though... The solution is shown below... Total Number of triangles = (n*n) + ( (n) * (n-1) * (4n+1) / 2 ) where n = (k+1) /2. K is the number of triangles on the each side. In the above example k is 3. k = 1 -> Total Triangles = 1 k = 2 -> Total Triangles = 4.875 ~ 5 k = 3 -> Total Triangles = 13 k = 4 -> Total Triangles = 26.875 ~ 27 k = 5 -> Total Triangles = 48 k = 6 -> Total Triangles = 77.875 ~ 78 and so on....

The simplest pattern is 2n+1, so the 16th figure will have 33 triangles. Of course, if you are creating new triangles and also keeping the old triangles, this would be different.
The ratio of two circles to three triangles is not a straightforward comparison as circles and triangles are different shapes. However, if we are comparing the areas of two circles to the combined areas of three triangles, we would need to calculate the area of each shape using their respective formulas (πr^2 for circles and 1/2 base x height for triangles) and then compare the total areas. The ratio would then be the total area of the circles divided by the total area of the triangles.

if a price cut decreases total revenue, demand is elastic. if a price cut decreases total revenue, demand is inelastic. if a price cut leaves total revenue unchanged, demand is unit elastic.
right angle triangles have a 90˙ angle as one of their angles. All triangles' angles have to add up to 180˙, so the total of the remaining 2 angles has to be 90˙. Other regular triangles are non-specific, their angles just have to add up to 180˙ total.
