anonymous · Answer

It would be great someone knew the answer. i'm kind of in a hurry...

anonymous · Answer

the tan B = 8/15 so find the atan (8/15)

anonymous · Answer

It didn't come out right..?

anonymous · Answer

$$\tan^{-1} \left( \frac{ 8 }{ 15 } \right)$$

anonymous · Answer

find this and you find the angle you need

anonymous · Answer

do you have a calculator on your computer?

anonymous · Answer

yes.

anonymous · Answer

use it

anonymous · Answer

you may have to put it into scientific mode

anonymous · Answer

I did , but it came out as ).57 or something.. and I was in degree mode.. :(

anonymous · Answer

that look more like radians...
on mine, I had to first divide 8 by 15 which gave .5333333333
and then push the inverse button and then the tan button

anonymous · Answer

let me try again :)

anonymous · Answer

I still got .5-

anonymous · Answer
