An unmanned rescue submarine is scanning the ocean floor from a height of 150 feet above the floor. The field of view of the scan is 40 degrees. What is the diameter of the circle captured by the scan at any one moment?
How would I do this? Please help!

Best ResponseYou've already chosen the best response.1perferably the one that uses the legs of the right triangle as its ratio

Best ResponseYou've already chosen the best response.0I am not sure which one that would be, cos sin or tan, this problem is a lot harder than any they've given us before.

Best ResponseYou've already chosen the best response.1well, we need one of those, define all all three for me, to the best of your recollection, ill correct if needed

Best ResponseYou've already chosen the best response.1tangent yes so: tan(a) = r/h what is r? and for that matter, what would a be as well?

Best ResponseYou've already chosen the best response.1your formulas are odd to me, soh cah toa is a memory device, and it seems that youve got them kind of in order ... toa would referet o: tan = o/a

Best ResponseYou've already chosen the best response.1tan(a) = r/h multiply both sides by h h tan(a) = r, and the diameter is just 2r

Best ResponseYou've already chosen the best response.0would the diameter then be 671.15? That seems a little high

Best ResponseYou've already chosen the best response.0tan(20) * 150 = r * 2 =671

Best ResponseYou've already chosen the best response.1150*tan(20) = radius 2*150*tan(20) = diameter you have your calculator in radian mode

Best ResponseYou've already chosen the best response.0multiply 671 by 180/pi?

Best ResponseYou've already chosen the best response.1sure, thats a simple fix, itll define it in degree mode that way
