Question

A ship is sighted from the top of a lighthouse. The angle of depression from the lighthouse to the top of the ship is 45 degrees. The distance from the top of the lighthouse directly to the ship is 4 miles. Calculate the horizontal distance of the ship from the bottom of the lighthouse. Put your answer to 2 decimal places

Answer 1

The hypotenuse is 4 and the angle is 45 degrees?
You can do it.

Answer 2

sin45 =x/4 x=sin45*4 x=2.83m

Answer 3

sin45 =x/4 x=sin45*4 x=2.83m for Rose

Answer 4

I think that is the height, not the distance, but it does not matter because with 45 degrees they are identical :)
