A) \[60{}^\circ \]
B) \[55{}^\circ \]
C) \[70{}^\circ \]
D) \[90{}^\circ \]
Correct Answer: B
Solution :
\[\text{BA}|\,\,|\text{CE}\] and \[\text{AC}\] is transversal \[\angle A=\angle ACE=60{}^\circ \] \[\angle ACB+\angle ACE+\angle ECD=180{}^\circ \] \[\angle ACB+60{}^\circ +65{}^\circ =180{}^\circ \] \[\angle ACB=180{}^\circ -125{}^\circ =55{}^\circ \]You need to login to perform this action.
