This question needs more information like where point E is but I'm going to assume that point E is directly below point D
With that assumption, angle EDF should be (90°- 25°) which is 65°
tan 65° = opposite/adjacent
tan 65° = 10 yd/ DE
DE = 10 yd/tan 65°
DE = 4.7 yd (to the nearest tenth)
Remember to include a picture next time for greater clarity :)
Since you can't take the square root of a negative number, we replace it with i:
√7/12 i
Hope this helps!
62.4 minutes is the answer
Answer: Option 'c' is correct.
Step-by-step explanation:
Since we have given that
Sample size = 865 = n
Number of voters favor approval of an issue before the legislature = 408 = x
So,
At 95% confidence level of significance, z = 1.96
So, confidence interval would be
Hence, option 'c' is correct.
