Rotate one of them so the right angle is in the same orientation as the other one.
1. AB = DE
2. CB = FE
3. AC = DF
4. Compare the length of two known sides: cb and EF
CB = 3 and EF = 8
8/3 = 2 2/3 scale factor
5. Ab is side de. Multiply the length of ab by the scale factor:
4 x 2 2/3 = 10 2/3
6. FD = sqrt ( 10 2/3^2 + 8^2)
FD = 13 1/3

Answer:
The confidence level is 95% or 0.95.
Step-by-step explanation:
Consider the provided information.
Results of a poll stated that 40% of U.S.
If you want to test the claim at alpha = 0.05.
As we know:
Confidence level = 1 - significance level (
)
Confidence level = 
Confidence level = 
Therefore, the confidence level is 95% or 0.95.

Answer:
-114
Step-by-step explanation:
f(x) = -4x^2 +5x
Let x = 6
f(6) = -4(6)^2 +5(6)
= -4(36) +30
- 144+30
= -114
