So 180 degrees means you are going to go a half of the circle clockwise dw:1379695755546:dw

Now tan(x)=sin(x)/cos(x) sin(x) and cos(x) are given to you in that picture for x=180 degrees

For number 2 its 4^2 + 3^2 = c^2 which equals 25 so c^2 = 5

Well no. Because tan(180 deg)=sin(180 degrees)/cos(180 degrees) You are only giving the me what cos(180 degrees) equals.

Let me show you a picture.

myininaya Group TitleBest ResponseYou've already chosen the best response.1
dw:1379696063163:dw cos(theta)=adj/hyp=x/1=x So the x coordinate is cos(theta) sin(theta)=opp/hyp=y/1=y So the y coordinate is sin(theta) tan(theta)=opp/adj=y/x Your coordinates are given to you when you do that 180 degree rotation.

Just put them in place of y and x.

tan(180 deg)=?

(1,0)

myininaya Group TitleBest ResponseYou've already chosen the best response.1
well plug those numbers remember tan(theta)=y/x

im sorry im so lost

myininaya Group TitleBest ResponseYou've already chosen the best response.1
what is y and what is x?
 one year ago

myininaya Group TitleBest ResponseYou've already chosen the best response.1
Remember your coordinates are (x,y) which means that x is 1 and y is 0. Just replace your x with 1 and replace your y with 0.

\[\tan(180^o) =\frac{\text{the y coordinate after rotating} 180^o}{\text{ the x coordinate after rotating} 180^o}\]

myininaya Group TitleBest ResponseYou've already chosen the best response.1
Replace that y coordinate with 0 Replace the x coordinate with 1 You know to do this since tan(theta)=y/x and your coordinate is (1,0)

So you should be able to do the last one. I will give you a hint use the same formula from above tan(theta)=y/x
