Answer:

5nm
Answer:
see explanation
Step-by-step explanation:
using the cofunction identity
sin x = cos(90 - x), hence
sin75° = cos(90 - 75)° = cos15°
Using trigonometric identities, sin^2(y) = 1 - cos^2(y).
If you substitute that in, you get 1- cos^2(y)/(1-cos(y)).
You can factorise 1 - cos^2(y) to be (1-cos(y))(1+cos(y)).
This means that the answer is 1 + cos(y) as the 1 - cos(y) will cancel.
Area=legnth times width
legnth=16 ft
width=3 ft
but wait, they want the area in squazre METERS
so convert feet to meters
1 foot=0.3048 meters
convert 16 feet and 3 feet to meters
16 feet=16 times 0.3048=4.8768
3 feet=3 times 0.3048=0.9144
so the area is now
legnth=4.8768 m
width=0.9144m
area=4.8768 m times 0.9144 m=4.45934592
round
4.0
answer is 4 square METERS
4 m^2
