A) \[{{80}^{o}},{{60}^{o}}\]
B) \[{{60}^{o}},{{40}^{o}}\]
C) \[{{80}^{o}},{{40}^{o}}\]
D) \[{{60}^{o}},{{80}^{o}}\]
Correct Answer: A
Solution :
\[\Delta \,\,ABC\cong \Delta XYZ\] \[\Rightarrow \] \[\angle A=\angle x={{180}^{o}}-({{60}^{o}}+{{40}^{o}})={{80}^{o}}\] Similarly, \[\angle y=\angle B={{60}^{o}}\]You need to login to perform this action.
