Answer: the polygon has 20 sides.
Step-by-step explanation:
The formula for determining the sum of the measure of the interior angles in a regular polygon is expressed as (n - 2) × 180.
if the sum of the measures of the interior angles is 3960
degrees. This means that
(n - 2) × 180 = 3960
Expanding the brackets by applying the distributive property, it becomes
180n - 360 = 3960
180n = 3960 - 360
180n = 3600
Dividing both sides by 180, it becomes
n = 3600/180
n = 20
Answer:
The 2nd choice ( the one that starts with square root of 5 )
Step-by-step explanation:
I turned all of the choices into decimals so they had the same playing field then I put them from least to greatest and I got square root of five, 5/2, 2.717171717171, 2 and 3/4.
Answer:
parallel: -1
y - 7 = -(x + 1)
y - 7 = -x - 1
y = -x + 6
Step-by-step explanation:
I would say b the reason is because -2 is on the x and -6 in on the y so it would be left then down.
