A) \[110{}^\circ \]
B) \[70{}^\circ \]
C) \[45{}^\circ \]
D) \[120{}^\circ \]
Correct Answer: B
Solution :
(b): \[\angle 2=\angle 4\] (Vertically opposite) \[\angle 4=\angle 8\] (Alternate angles) \[\angle 8=\angle 6\] (vertically opposite angles) \[\therefore \text{ }\angle 2=\angle 4=\angle 6=70{}^\circ \]You need to login to perform this action.
