Angle of the vertex of the combined shapes so far (without n sided) = $360 - (90 + 120 + 60) = 90.$ so we need a shape that has angle side 90 to finish the 360 degrees. therefore, it is a square: with 4 sides. it is an n-sided polygon, so n = 4
THANK YOU SO MUCH!!!!!!!!!
I had no idea it was that simple... ELEGANT solution
OOPS i didnt see this solution when i posted mine! great they are the same though :)
We have P = k(14,7) where P = pressure and k = the rate
at 0 feet is 14.7 lb
calculate, the pressure increases at a rate of 0.441 psi for each foot you descend.
mile is 5280 feet
so 14.7 + 5280(0.441) = ~2343.2 psi
The minimum possible value is 70 - 50 = 20%, and MAXIMUM is 30 + 50 = 80%
difference = |80 - 20| = 60
there's three UNDEFINED terms we have: point, plane, and line.
point: no size, but has location
plane: infinite size, extends infinitely in two dimensions.
line: no width, extends infinitely in one dimension.
answer is plane
Minimizing, to obtain t^2-9t-36 = -225/4. The value of t is 9/2
For the first, we find n^2 = 28, n < 0 so it is n = -2√7.
For the second, we have 6 - 2n = 0, n >= 0 so it is n = 3
|-2√7 - 3| = 3 + 2√7
