Answer:
1120°
Step-by-step explanation:
Use the sum of interior angles formula:

Where n is the number of sides.
In a nonagon, there are 9 sides, substitute 9 for n:

Since our nonagon is a regular nonagon, all 9 angles measure the same, so each angle measures:

Subtract 140 from 1260:

Answer:
11 = Y+5
Step-by-step explanation:
Answer:
ok so the probility of gettting one white fish is
13/23
and if we take out one white fish the problity is
12/22
so we just multiply
12/22*13/23=0.30830039525
so the problity is 0.30 if you choose two fish you will get white for both
Line them up
3x3= 9, 3x2= 6, 3x5= 15
Add a 0 under the 9, 7x3= 21, leave the 1 and carry the 2, 7x2= 14+2= 16 leave the 6 and carry the 1, 7x5= 35+1= 36
9+0= 9, 6+1= 7, 5+6= 11 leave 1 carry 1, 1+6= 7+1= 8, 0+3= 3

+ 36,610
———
38,179
Replace x with -2 in the equation and solve.
3(-2) +1 = -6 + 1 = -5
