A) \[105{}^\circ ,125{}^\circ ,55{}^\circ \]
B) \[125{}^\circ ,55{}^\circ ,125{}^\circ \]
C) \[125{}^\circ ,125{}^\circ ,55{}^\circ \]
D) \[25{}^\circ ,135{}^\circ ,135{}^\circ \]
Correct Answer: C
Solution :
\[\angle A+\angle B=180{}^\circ \] \[\because \] \[\,AD||BC\] \[\therefore \]\[\angle B=180{}^\circ -55{}^\circ =125{}^\circ \] Also, \[\angle B=\angle D=125{}^\circ \] \[\angle A=\angle C=55{}^\circ \]You need to login to perform this action.
