Most likely, polygon <span>ABCD</span> has sides of known lengths.
It is also likely that one of the sides of polygon <span>EFGH</span> (not <span>EH</span>) is also known. For instance, its side <span>EF</span>.
If the above is true, we can find the scaling factor as a ratio between lengths of corresponding sides:
<span>r=<span><span>EF</span><span>AB</span></span></span>
Since this ratio is constant for any two corresponding lengths,
<span>r=<span><span>EH</span><span>AD</span></span></span>
From the last two equations we can derive:
<span>EH=AD⋅<span><span>EF</span><span>AB</span></span></span>
Hope That Helped : ) (Took a minute)
The solution to the problem is as follows:
<span>cos2A - cos4A = -2 sin(6A/2).sin(-2A/2) = +2 sin(3A).sinA
and
sin4A - sin2A = 2 cos(6A/2).sin(2A/2) = 2 cos(3A).sinA
Hence RHS = (cos(2A)-cos(4A))/ (sin(4A)- Sin(2A)) = sin 3A / cos 3A = tan 3A = LHS

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!
X=2 my friend
hope this helps!
The formula to solve these is the square root of X x Y, So the problem would be 242 * 8 which = 1,936. Then you find the square root of 1,936 which = 44 . So that is your answer :) Hope it helps
Answer:
Confidence Interval : 2.72% < p < 6.48%
Step-by-step explanation:
Number of randomly selected deaths = 669
Number of deaths caused by accident = 31
z-score for 98% confidence level = 2.326
Confidence Interval : 0.046 - 0.0188 < p < 0.046 + 0.0188
: 0.0272 < p < 0.0648
: 2.72% < p < 6.48%
Hence, Confidence Interval : 2.72% < p < 6.48%
