so, is a semi-circle, half a circle, recall a circle has a total of 360°, so half of that will be 180°.
the diameter of that circle is 10, so its radius is half that, or 5.
Answer:
Step-by-step explanation:
If we draw a right angle triangle ABC,
where B is the vertex with 90 degrees.
A is the top of the lighthouse
C is the waterline of the ship.
we can write the sidelengths of this triangle.
AB = 152
BC = 868.
to find the angle of depression, all we need to find is the angle BAC and subtract it from 90 degrees.
to find the angle BAC, we'll use trigonometric functions.
we don't have the hypotenuse of the triangle, and we won't be needing it either. we'll use tan
} = \dfrac{BC}{AB}[/tex]
} = \dfrac{868}{152}[/tex]
to find the angle of depression:
You can do 2*4*3*17 that is 408.
