Any polygon given by a list of 2D vertex coordinates has area given by the shoelace formula.
That's the absolute value of half the sum of the cross products of the sides. We form the table of the vertices. We include the first vertex at the end, then calculate the cross product of the side, (a,b) then (c,d) gives cross product ad-bc.
cross product
-4 3 0
0 0 0
6 8 6(11)-8(2) = 66 - 16 = 50
2 11 2(3) - (11)(-4) = 50
-4 3
So the area is (1/2)(50+50) = 50
Answer: 50
Answer:
angels on a triangle = 180°
so you add 75 and 50 which gives you 125 then u take away that by 180 to find x (Just the process)
and that's your answer
Answer:
The first one is
5x * 10
(x is the variable) TIMES 10
Step-by-step explanation:
13 quarters = 13 *0.25 = 3.25
3.60 - 3.25 = 0.35
0.35 = 0.25 +0.10
he has 1 dime and 14 quarters
Answer is B
