A) \[50{}^\circ \]
B) \[60{}^\circ \]
C) \[80{}^\circ \]
D) \[75{}^\circ \]
Correct Answer: A
Solution :
(a): They are congruent \[\Rightarrow \,\,\,\angle A=\angle F;\]Now \[\angle A=180{}^\circ -60{}^\circ -70{}^\circ =50{}^\circ \] \[\therefore \,\,\,\angle F=50{}^\circ \]You need to login to perform this action.
