Calculate the 365+365 then do it in the calculation then get the answer the number the loan off
The ship is 394.73 fr far from the base of the lighthouse.
According to the given question.
Angle of depression from the top of the light house is 21 degrees.
Let ∠ABC represents the angle of depression. And BC be the distance of ship from the base of light house.
Now in triangle ABC we have
tan 21 = AC/BC
⇒ 0.38 = 150/BC
⇒BC = 150/0.38
⇒ BC = 394.73ft
Hence, the ship is 394.73 fr far from the base of the lighthouse.

Answer:
Step-by-step explanation:
L.H.S= (x-y)২
=(2-1)২
=1
R.h.s=x২-2xy+y২
=4-4 +1
=1
Haha..It was so easy
Answer:
y= x squared.
Step-by-step explanation:
When graphed, the parabola only has an x-intercept at (0,0). Since a root is another word for an x-intercept, it only has one root.
I hope this helps, and I hope you have a good day.
Answer: 9.97
==============================================
Explanation:
y = distance from the base of the pole to the closest person
y+200 = total horizontal distance
-------------
Focus on the smaller right triangle.
tan(angle) = opposite/adjacent
tan(26) = 55/y
y*tan(26) = 55
y = 55/tan(26)
y = 112.76671 approximately
Make sure your calculator is in degree mode.
--------------
Now move to the larger right triangle
tan(angle) = opposite/adjacent
tan(x) = 55/(y+200)
tan(x) = 55/(112.76671+200)
tan(x) = 55/312.76671
tan(x) = 0.17585
x = arctan(0.17585) same as
x = 9.97349
x = 9.97 degrees approximately
