A) \[{{185}^{o}}\]
B) \[{{134}^{o}}\]
C) \[{{148}^{o}}\]
D) \[{{176}^{o}}\]
Correct Answer: A
Solution :
\[\angle FCA=\angle BFD\] (Corresponding angles) \[\Rightarrow \] \[x={{51}^{o}}\] Now, in \[\Delta ABC\] \[y={{51}^{o}}+{{83}^{o}}\] (Exterior angle property) \[\Rightarrow \] \[y={{134}^{o}}\] So, \[x+y={{51}^{o}}+{{134}^{o}}={{185}^{o}}\]You need to login to perform this action.
