A) \[160{}^\circ \]
B) \[155{}^\circ \]
C) \[150{}^\circ \]
D) \[145{}^\circ \]
Correct Answer: C
Solution :
\[\angle ABC=\angle BCD\] as \[AB||CD\] \[\angle BCD=65{}^\circ \angle ECD=65{}^\circ -\angle BCE=65{}^\circ -35{}^\circ \]\[=30{}^\circ \] \[\angle CEF+\angle ECD=180{}^\circ \] \[\angle CEF=180{}^\circ -30{}^\circ =150{}^\circ \]You need to login to perform this action.
