Best ResponseYou've already chosen the best response.0there is not enough information in your problem. Did they give a distance such as from the tree to the end of the depression or any lengths?

Best ResponseYou've already chosen the best response.0are you sure? that makes no sense. if its 36 feet its solvable but according to your diagram you have a right angle there which is 90 degrees...

Best ResponseYou've already chosen the best response.036 feet with 25 degrees im sorry i just started and im still new to all this

Best ResponseYou've already chosen the best response.0so sin is used to find length opposite of the angle in a right triangle and cos for adjacent length. (disregarding the hyp). so here you would use 36*sin(25) to yield the height of the tree.

Best ResponseYou've already chosen the best response.0if you were given the height and wanted to find the length of the shadow you would use height*(cos(25))

Best ResponseYou've already chosen the best response.0no  that is not correct I think I waould assume th e36' is the length of the shadow so it is TAN 25° you want

Best ResponseYou've already chosen the best response.036*tan(25) my head is somewhere else sorry about that.

Best ResponseYou've already chosen the best response.0so i type the equation you put into the calculator correct?

Best ResponseYou've already chosen the best response.0so by typing in 36*tan(25 i recieved 4.80

Best ResponseYou've already chosen the best response.0better still  you understand the equation and why we used tan 25 THEN you put it in your calculator

Best ResponseYou've already chosen the best response.0what do you mean? im really bad at math and have a slow mind set

Best ResponseYou've already chosen the best response.0for instance: it tells you the angle of depression SO how do we get the angle 25 as I drew (those are just excuses)

Best ResponseYou've already chosen the best response.0we find a way to use the 36? or get rid of it?

Best ResponseYou've already chosen the best response.0ok so there are three equations for right triangles you should keep in your head to memory. sin(angle) = opposite/hypotenuse ; cos(angle) = adjacent / hypotenuse ; and tan(angle) = opposite/adjacent. utilizing these you can solve any problem involving a right triangle if you are given one length and one angle. In this case you are given 25 degrees and the length adjacent to that angle. You are asked to find the height which is opposite to that angle thus you can use tan(angle) = opposite/adjacent solve for opposite yielding tan(angle)*adjacent = opposite or tan(25)*36 = answer. To check your answer you use cos(25)/36 = hypotenuse and then use pythagreas theorem and you should come out with the same answer for the height.

Best ResponseYou've already chosen the best response.0do oyu understand the 3 functions in a right angle triangle? sin cos tan (it is not 23.4 so I think you are guessing)
