The length of the sunken ship is given by...

 200/tan(56) - 200/tan(62) = about 28.56  meters long

Use the " x^y " key...Type the base, then, hit this key and type your exponent. Then, hit " =" or the "enter" key on your keyboard.

We can use the tangent for this..

tan (10° )  = about .176 = m = the slope

This means that y changes by about .176 when x changes by 1...

This is a famous sequence (series) that has many applications in nature, art, etc.

The first few terms are..... 0 , 1, 1, 2, 3, 5, 8, 13.....

Notice that, afer the first two given terms, each successive term is just the sum of the previous two...!!

If the sides of the perimeter are integers, 1 is the minimum side length of any particular side. So, 49 would have to be the length of the adjacent side.....

Note  1 + 49  + 1 + 49 = 100 = the perimeter

So... the minimum square area would be (1) (49) = 49 square units...

It has to do with something called the "Power Law".....simply put....larger values in data sets ( such as tall mountains, etc.) are more rare than "smaller" mountains.

Consider the weights of most adults......most start with a "1" or a "2"....and there are fewer that start with a '3"....and fewer still that start with a"4".....

That's about as much as I know about this.....

The first 6

1 + 2 + 3 + 4 + 5 + 6  = 21

I think you mean you'd like to write this in exponential form.....so we have.....

8⁰ = 1

And that's it.....
