Answer 1

how many radians in \(180^o\)?

Answer 2

anyhow... look at your Unit Circle
there's one \(\pi\) radians\ in \(180^o\)

Answer 3

I actually do not know, im looking at the unit circle right now

Answer 4

\(\begin{array}{ccllll}
radians&degrees
\\\hline\\
\pi &180\\
x&-450
\end{array}\implies \cfrac{\pi }{x}=\cfrac{180}{-450}\)

Answer 5

so, just solve for "x"

Answer 6

okay so it would be -5pi/2?

Answer 7

yeap
