there is not enough info to answer this is there a sketch or a dimension you have missed out?
there 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?
sorry its a bad drawing but thats literally what it gives me
is that 36 degrees or 36 ' or 36 " ?
a.16.8 feet b.18.2 feet c.23.4 feet d.39.7 feet
are 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...
36 feet with 25 degrees im sorry i just started and im still new to all this
so 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.
if you were given the height and wanted to find the length of the shadow you would use height*(cos(25))
no - that is not correct I think I waould assume th e36' is the length of the shadow so it is TAN 25° you want
yeah youre right my fault.
36*tan(25) my head is somewhere else sorry about that.
so i type the equation you put into the calculator correct?
so by typing in 36*tan(25 i recieved -4.80
better still - you understand the equation and why we used tan 25 THEN you put it in your calculator
what do you mean? im really bad at math and have a slow mind set
for instance: it tells you the angle of depression SO how do we get the angle 25 as I drew (those are just excuses)
we find a way to use the 36? or get rid of it?
everyone is bad at maths until they Learn how to do it
we all have to start somewhere i guess
ok 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.
do oyu understand the 3 functions in a right angle triangle? sin cos tan (it is not 23.4 so I think you are guessing)
