Question

Which trig factor should i use on this triangle? HELP PLEASE

Answer 1

oo cool hair c:

Answer 2

Thanks man, can you help me?

Answer 3

So to solve for x, we want to relate the side `opposite` and the side `adjacent` to our angle 35 degrees.

Answer 4

Which trig function deals with `Opp` and `Adj`? :o

Answer 5

tangent?

Answer 6

Yesss, good good good.

Answer 7

Understand how to set it up?

Answer 8

35tan(12
?

Answer 9

The tangent of our angle is equivalent to the ratio of the opposite side to the adjacent side.

\[\Large \tan \theta\quad=\quad \frac{opp}{adj}\]

Looks like in this case, our setup will be,\[\Large \tan35^o\quad=\quad\frac{x}{12}\]
Understand how I came to that setup? :O

Answer 10

Yes :0 because x is opposite of the angle and 12 is the adjacent leg

Answer 11

cool.
So how do we solve for x now? Hmm..

Answer 12

move x to the other side and use a calculator ;D

Answer 13

no no no careful! \:D/ move 12 to the other side!
but ya, calculator to finish it up seems good :3

Answer 14

damn so 35 tan times 12

Answer 15

I'm not sure what 35 tan means. That's kind of a sloppy way to write that.
Try to get used to saying tan35 times 12 instead.
I think that's what you meant at least. :)

Answer 16

i keep getting negative numbers.

Answer 17

Hmm is your calculator in `Degree Mode` ?

Answer 18

im not sure its just the calculator on my boyfriends phone :/

Answer 19

oh boy you silly billy +_+
maybe google has a calculator you can use, hmm lemme think.

Answer 20

ya do a google search for calculator, the google calculator has a radians/degree switch :D

Answer 21

Lol im just trying to cram cause im moving tomorrow morning and i just wanna finish this lol

Answer 22

\[
12\tan(35^\circ)=\dots
\]
