A) \[35{}^\circ \]
B) \[55{}^\circ \]
C) \[70{}^\circ ~\]
D) \[110{}^\circ \]
Correct Answer: B
Solution :
[b] In\[\Delta \,ABC,\] \[\angle \,ABD=\angle \,ACD\] = Equal angles of isosceles triangle \[\angle \,A=180-\angle B+\angle C=180-35-35=110{}^\circ \] since, AD is the median \[\therefore \] \[\angle \,BAD=\frac{\angle A}{2}=\frac{110}{2}=55{}^\circ \] |
