A) \[50{}^\circ \]
B) \[60{}^\circ \]
C) \[70{}^\circ \]
D) \[90{}^\circ \]
Correct Answer: A
Solution :
\[\angle CBF=\angle CDA\] \[\Rightarrow \] \[\angle CDA=130{}^\circ \] \[\angle CDA+x=180{}^\circ \](linear pair) \[x=180{}^\circ -130{}^\circ =50{}^\circ \]You need to login to perform this action.
