Calculate the whole circle angle $($i$.$e$.$ with reference to line TBM $1-$A$)$ for the angle measured at point C$,($angle BCD$)$ and express it as a decimal to $4$ decimal places $($enter the angle, in degrees, as a decimal rather than expressing it in degrees, minutes and seconds: $\backslash$deg $)$An instrument was set up over TBM $1,$ and backsights onto point A before sighting onto $B.$ The instrument was then moved to $B,$ back$-$sighted onto TBM $1$ and then sighted at C$.$ It was moved once again, to $C,$ back$-$sighted onto B before being sighted onto $D.$ The line between TBM $1$ to point $A$ is to act as the reference plane for the site $($taken as zero degrees: $00^{\text{'}}{0}^{\text{'}\text{'}}.$ Note that the instrument would not provide the ability to zero the horizontal angles before taking a reading.
