as viewed from Cliff 360 m above sea level the angle of depression of a ship is to 28° how far is the ship from the shore
andrezito [222]
The distance of the ship from the shore is given by:
tan θ=opposite/adjacent
θ=28°
adjacent=x
opposite=360 m

substituting the values in our equation we get:
tan 28=360/x
solving for x we get
x=360/tan 28
x=677.06 m

alexdok [17]

Answer: Eliza wakes up at 6:25 A.M.

(x-1)2 + (y + 3)2 = 73<br> What is the center ?
Olenka [21]

Answer:

centre = (1, - 3 )

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

(x - 1)² + (y + 3)² = 73 ← is in standard form

with (h, k ) = (1, - 3 ) ← centre
