Trig Problem
Hello,

I have a trig worksheet to do and i am stuck on question 3 and 6.

Question 3 states: Through how many radians does a wheel of radius one travel if it travels 5 feet down the road.

I know the circumference of the circle is 2pi. but how do i find out how many times does it rotate?

Question 6 states: If the $\tan x=1$, what is $\cos x$ and what is $\cot x$?

i know that $\tan=\frac {opposite}{hypotenuse}$ and that $\cos=\frac {adjacent}{hypotenuse}$ and $\cot= \frac {adjacent}{opposite}$. So would everything be 1? 1=hypotenuse/adjacent/opposite?

I have attached my one page worksheet if you did not understand. Also if you could make sure the other problems are correct, then that would be great.

I greatly appreciate everybodies help.

Thank YouAttachment 4889

Draw a triangle with opposite and adjacent equal. What's the hypotenuse?

O, i see, the hypotenuse is $\sqrt 2$. Thank you, do you have any feedback for question number 3?

Thanks again.
