Consider the angle shown below with an initial ray pointing in the 3-o'clock direction that measures θ radians (where 0≤θ<2π). The circle's radius is 2 units long and the terminal point is (−1.79,−0.89).The terminal point is how many radius lenghts to the right of the circle's center?h= radii   Then, cos−1(h)=Does the number we get in part (b) give us the correct value of θ? Therefore, θ=

Given the terminal point ( -1.79 , -0.89 )

So, the x- coordintes = -1.79


\begin{gathered} \theta=\cos ^(-1)h \\ \\ h=-(1.79)/(2) \\ \\ \theta=\cos ^(-1)(-(1.79)/(2))=206.5^o \end{gathered}
