The angle of depression from the top of a lighthouse to a boat is 27*. if the direct distance from the top of lighthouse to the boat is 462 ft, find the distance from the base of the lighthouse to the boat
1 answer:
Answer:
Correct answer: Db = 411 .18 ft
Step-by-step explanation:
Given:
α = 27° angle of depression
Dt = 462 ft distance from the top of lighthouse to the boat
Db = ? distance from the base of the lighthouse to the boat
Here we have a right triangle with hypotenuse Dt and one leg Db.
By definition
cos α = Db / Dt ⇒ Db = Dt · cos α
Db = 462 · cos 27° = 462 · 0.89 = 411 .18 ft
Db = 411 .18 ft

1. Solve for N
Add all terms together and set equal to 360
(4n)+(9n+2)+(8n-12)+(5n+6)=360
26N= 364
N= 14
M<A = 4(14)= 56
2.9(14)+2=128

we know that
the volume of a solid oblique pyramid is equal to
where
B is the area of the base
h is the height of the pyramid
in this problem we have that
B is a square
where
