I did tan = 10540/250
but I don't know if that is correct.
Hello, aikenfan!
Code:* - - - - - - - - - - - | * α | * 250 | * | * | * | θ * *---------------------------* : - - - - 10,560 - - - - - :
The angle of depression is $\displaystyle \alpha$ . . . which equals angle $\displaystyle \theta.$
And: .$\displaystyle \tan\theta \:=\:\frac{250}{10.560}$
Got it?
