The sum of the interior angles, s, in an n-sided polygon can be determined using the formula s=180(1-2), where n is the
number of sides
using this formula, how many sides does a polygon have if the sum of the interior angles is 1.260"? round to the nearest
whole number

i need the options

step-by-step explanation:

i found two solutions,   n = 2 • ± √3 = ± 3.4641

step-by-step explanation:

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
