The maximum wingspan in millimeters would be 160.
The prefixes, Kilo, Hecto, Deca, Deci, Centi, and Milli all increase by powers of ten. An easy way to remember this is
King Kilo
Henry Hecto
Died Deca
Drinking Deci
Chocolate Centi
Milk Milli
Since Centi is greater than Milli by one space, you increase by ten, which means you move the decimal once to the right.
Hope this helps! :)
Answer:

Step-by-step explanation:
We need to find 
We know that √-1 = i
Adding -49 and -4 and solving

Since 53 is not a perfect square so our answer is:

base, b = 45m
angle of elevation, aoe = 82deg
height at 86th floor, h1
height above 86th floor, h2 = 123m
total height, h = h1 + h2
using
tan (aoe) = h1/b
=》 h1 = tan (aoe) × b = tan 82 x 45 = 320.2
h = h1 +h2 = 320.2 + 123 = 443.2m
8 feet
If 1 inch is 4 feet, multiply 4 times 2, and you will get 8.
