The sum of the interior angles of a polygon with N sides is (N-2) x 180 degrees.
For a 30-gon, the sum of interior angles is (28) x (180) = <u>5,040 degrees</u>.
It makes no difference whether or not the polygon is convex at every vertex.
Answer:
First do the Base multiplied by the Height.
After divide by 2
Step-by-step explanation:
Furthest from 0, so I am going to take the absolute value of these numbers. The absolute value will tell us how far away from 0 these numbers are.
|-1/2| = |- 0.5| = 0.5
|8/9| = |0.88| = 0.88
|0.2| = 0.2
so the number furthest from 0 is 8/9
Answer:
1) the factored form is y= ( x-5 ) ( x+4 )
2) the vertex is (4.5, -0.25)
3) the y intercept is when x equals 0 so it is at (0,20)
4) it opens upward and the vertex is (4.5, -0.25) the x intercepts are (4,0) and (5,0) and the y intercept is (0,20)
5)
a. it dips between 4 seconds and 5 seconds so the x intercepts are (4,0) and (5,0)
b. it is taken at the vertex aka the lowest point so the height is -0.25
3 1/2 is equal to 7/2. 1 1/2 is equal to 3/2. 7/2 times 3/2 is equal to 21/2, which is equal to 10 1/2.
