1,2,3,4,6,7,8. This is the answer
Recall that for a polygon to have 180° as the sum of its interior angles, then it must have three sides and thus a triangle. And similarly, for a polygon to have a sum of 360°, it must have four sides or it is a quadrilateral.
[Note that for larger angles, we can apply the formula 180(n - 2) to find the total sum of the interior angles. n is the number of sides]
Now, since we're comparing a four-sided and three-sided polygon, this means that they only differ by 1 side.
Answer: A. 1 side
Answer:
1/6 and 3/6
Step-by-step explanation:
a dice has up to 6 sides making it a 1/6 chance for landing ona four. and then making it a 3/6 chance for landing on a even number
Answer:
a
Step-by-step explanation:
Given
3(x + 3)² - 81 = 0 ( add 81 to both sides )
3(x + 3)² = 81 ( divide both sides by 3 )
(x + 3)² = 27 ( take the square root of both sides )
x + 3 = ± 
= ± 3
( subtract 3 from both sides )
x = - 3 ± 3
x = - 3 - 3 or x = - 3 + 3 → a
