Answer:
the answer is 1
Step-by-step explanation:
2^(3/2) - 7 + /-4/
2^(3/2) - 7 + 4
2^(3/2) - 7 + 2^2
2^(3/2) + 2^2 - 7
laws of indices reversed
2^(3/2×2) - 7
2^3 - 7
8 - 7

Answer:
0.0909 = 9.09%
Step-by-step explanation:
Initially we have a total of 12 socks, where 4 are green, so the probability of grabbing a green socks is 4/12.
Then, as there is no replacement, we have 11 socks, where 3 are green, so the probability of grabbing again a green socks is 3/11
So the probability of both socks being green is:
P = (4/12) * (3/11) = 1/11 = 0.0909 = 9.09%
- B = E
- C = F
- A = D
- AC = FD
- BC = FE
- AB = ED
These are all your congruent parts and they are colour coded along with matching marks on the triangle to help you know that! :)
Sum of all angles is 150
One angle you have subtract from 150
Then take THAT answer and divide by 2!
