A) \[{{90}^{o}}\]
B) \[l||m,\]
C) \[{{130}^{o}}\]
D) \[{{50}^{o}}\]
Correct Answer: B
Solution :
Since, \[{{60}^{o}}\] \[{{30}^{o}}\] \[{{80}^{o}}\] (Corresponding angle) Given: \[{{100}^{o}}\] where \[\angle DAC={{54}^{o}}\] (By using sum of angles of \[\angle ACB={{63}^{o}}\]) \[\angle BAC\] \[{{72}^{o}}\] \[{{54}^{o}}\]You need to login to perform this action.
