A) \[26{}^\circ \]
B) \[13{}^\circ \]
C) \[23{}^\circ \]
D) \[46{}^\circ \]
Correct Answer: B
Solution :
Draw a line \[EF|\,\,|AB,\]\[EF\] is also parallel to CD \[\{\text{as}\,AB|\,\,|CD\}\] \[4x=\angle A\] (Corresponding angles) \[6x=\angle B\] (Corresponding angles) \[10x=\angle A+\angle B=130{}^\circ \] \[x=\frac{130{}^\circ }{10}=13{}^\circ \]You need to login to perform this action.
