Answer:
B
Step-by-step explanation:
I hope this helps let me know if wrong
We can write this as
9×8×7×6×5×4×3×2×1=9!
. We can also write this as a permutation, with the general formula being:Pn,k=n(n−k
And so we'd get:
P9,9=9!(9−9)!=9!1=9!
The probability is 1/9
16
16+4x = 10 +14
-16 -16
4x = 8
/4 /4
x=2
8x=8(2)
=16
8x2
a = 540°
b= 180°
a= pentagon has 5 sides which means 180 × 5= 540
b= 540÷5=180
