tangent =opposite/adjacet
so opposite of C is sqrt5 and the adjacent is 3 (since the other is the hypotenuse)
so we get tangent=sqrt5/3 which is answer B.

anonymous · Answer

That's what I got! Thanks!

anonymous · Answer

could you help me on one more? I'm just learning this.

anonymous · Answer

sure, one sec.

anonymous · Answer

for this one, since you already have two sides, its easiest to use the pythagorean theorem so a^2+b^2=c^2 meaning... |dw:1360300169762:dw|

anonymous · Answer

can you figure it out from there?

anonymous · Answer

do I have to find the square root of 4688?

anonymous · Answer

okay so we multiply 8 times 8 to get 64 and we multiply 68 times 68 to get 4624
from there we add to get 4688=x^2 then, to get rid of the squared sign over the x, you take the square root of bth sides, so yes!

anonymous · Answer

Yup. This is where I'm stuck. Lol.

anonymous · Answer

It's A isn't it?

anonymous · Answer

so it looks like in the answers you cant just use a calculator, you need to simplify it as much as possible so...|dw:1360300425846:dw|

anonymous · Answer

i believe it is D

anonymous · Answer

ohhh! thank you. Gosh. I'm keeping that as an example.

anonymous · Answer

your welcome! When i learned this, i had trouble too! dont worry, enough practice and you'll have it down! :D
