In a diagram,
And, in general, the initial side of an angle is the x-positive axis; in this case, the line that goes from the center to the east. Therefore,
Let theta be the orange angle; then,
[tex]\begin{gathered} \theta=90\degree+90\degree+90\degree+45\degree=315\degree \\ \Rightarrow\theta=315\degree \end{gathered}[/tex]
Thus, the answer is 315°
