Angle of elevation= 61°
Height of Sarah =h = 5.5ft
Distance(from base of statue) between Sarah and statue = 166 ft
Now,
tan(61°)= H/166
H= 299.47 ft
but in the height H you also add the height of of Sarah then you get the height of statue.
Height of <span>statue of the liberty = H+h
= 299.47+5.5
= 304.97 ft</span>
Answer:
90 -63=27 so the answer is 27 because complementary angles add to 90
Answer:
<u>Given :</u>
length offshore = CS=√(1+X^2)
Cable charged = 5000√(1+X^2)
onshore length = 4-X
laying cost = 3000(4-X)
total cost:
C=5000√(1+X^2) +3000(4-X)
DC/DX
= [5000*(0.5)*2X/{√(1+X^2)}]-3000=0... for optimum
5000X=3000√(1+X^2)
25X^2=3+3X^2
22X^2=3
X=√(3/22)
= 0.3693 miles
So, it would be laid offshore to S in a manner that
BS=X=0.3693 miles
Onshore=4-0.3693
=3.6307 miles
The solution is greater than one but less than or equal to 8.
121.50 divided by 9 is 13.50. 13.50 times 5 equals 67.50
