Triangle ABC with angle x at A. AC is extended to D and BC is extended to E. The reflex angle at B is 298° and angle ECD is 97°

Diagram NOT accurately drawn

\(ABC\) is a triangle.
\(D\) and \(E\) are points such that \(ACD\) and \(BCE\) are straight lines.

reflex angle \(ABC = 298^\circ \)
angle \(ECD = 97^\circ \)

Work out the size of angle \(x\).
Give a reason for each stage of your working.
