Question

HELP use the pythagorean theorem and/or trigonometry to solve the following word wordproblems. Layne spots a sailboat from her 5th floor balcony , about

25m above the beach at an angle of depression of 3 degrees to the nearest meter , how far out is the boat

Answer 1

I'm going to use just trig for this one.

so basically, you're going to find the adjacent side of a triangle by using the other side, so you would use tangent.


`Tan30= (25)/(X)`

then just rearrange and solve for X


`X=(25)/(Tan30)`

And the answer is 43.3 i think.



If i'm wrong please correct me
