Which polygon has interior angles whose sum is 1440°? octagon nonagon decagon 11-gon

ArbitrLikvidat [17]

Answer:

Decagon

Step-by-step explanation:

We can use the general equation to determine the sum of interior angles:

$I.A. = 180 \times (n-2)$

Since we know the sum of interior angles (I.A.) is 1440°, we must figure out n - the number of sides and so:

$1440=180(n-2)\\\\\frac{1440}{180}=n-2\\\\8=n-2\\\\n=10$

Since n=10 this means that it is a 10 sided shape meaning it's a decagon.
