Answer:
Never
Step-by-step explanation:
Using the formula to find the sum of the interior angles, (n-2) * 180, we can work backwards.
300/180 +2 = 11/3 or 3.666. Polygons cannot have decimal sides therefore your answer is never.
If you have a ratio like 1 yard for 3 feet you can graph that to get a better understanding of size

could i have brailiest plz it isnt a must tho thx
Answer:
(a) true
(b) true
(c) false; {y = x, t < 1; y = 2x, t ≥ 1}
(d) false; y = 200x for .005 < |x| < 1
Step-by-step explanation:
(a) "s(t) is periodic with period T" means s(t) = s(t+nT) for any integer n. Since values of n may be of the form n = 2m for any integer m, then this also means ...
s(t) = s(t +2mt) = s(t +m(2T)) . . . for any integer m
This equation matches the form of a function periodic with period 2T.

(b) A system being linear means the output for the sum of two inputs is the sum of the outputs from the separate inputs:
s(a) +s(b) = s(a+b) . . . . definition of linear function
Then if a=b, you have
2s(a) = s(2a)

(c) The output from a time-shifted input will only be the time-shifted output of the unshifted input if the system is time-invariant. The problem conditions here don't require that. A system can be "linear continuous time" and still be time-varying.

(d) A restriction on an input magnitude does not mean the same restriction applies to the output magnitude. The system may have gain, for example.
we know is a right triangle, so one angle must be 90°, we also know is an isosceles, that means it has twin sides, and we also know that the hypotenuse or slanted side is 8, so the triangle must be a 45-45-90 triangle, Check the picture below.
