A) \[160{}^\circ \]
B) \[155{}^\circ \]
C) \[150{}^\circ \]
D) \[145{}^\circ \]
Correct Answer: C
Solution :
\[\angle ABC=\angle BCD\,\,as\,\,AB||\,CD\] \[\angle BCD=65{}^\circ \] \[\angle ECD=65{}^\circ -\angle BCE\] \[=65{}^\circ -350=30{}^\circ \] \[\angle CEF+\angle ECD=180{}^\circ \] \[~\angle CEF=180{}^\circ -30{}^\circ =150{}^\circ \]You need to login to perform this action.
