Answer:
272.17 ft
Step-by-step explanation:
Since the angle of depression of the sighting equals the angle of elevation of the lighthouse from the boat, using trigonometric ratios,
tanθ = x/d where θ = angle of sighting, x = height of lighthouse =55 ft and d = distance of boat from lighthouse at sighting
So, d = x/tanθ
when θ = 8.1°, for the first sighting,
d₁ = 55/tan8.1 = 386.45 ft
when θ = 25.7°, for the second sighting,
d₂ = 55/tan8.1 = 114.28 ft
The distance the boat traveled between the two sightings is thus d₁ - d₂ = 386.45 ft - 114.28 ft = 272.17 ft
Answer:
Length of shadow = 35.56 ft
Step-by-step explanation:
∠ BAC = 68°
Height of building = BC = 88 ft
Length of shadow = AC = ?
Answer:
2= 27625 3=25350
Step-by-step explanation:
All you do is plug in 2 into the equation and then after the answer you plug in 3.
For example: v(2)=32500(0.92)^2
0.92^2= 0.8464 or 0.85
32500(0.85)= 27625
same with the 3
v(3)=32500(0.92)^3
(0.92)^3= 0.778688 or 0.78
32500(0.78)=25350
Hope this helps!!
