Question

The angle of depression from the top of a 64 ft tall tower to a deer is 47 degrees 16 minutes. find the distance from the deer to the bottom of the tower ?
-its a right triangle the right angle is at C

Answer 1

lets draw a picture

Answer 2

you need the other angle up top which you get by subtracting 47 degrees 16 minutes from 90 degrees

Answer 3

then
\[\tan(42^o44')=\frac{x}{64}\] and so
\[x=64\tan(42^o44')\] whatever that is
