A) \[{{80}^{o}},\,\,{{65}^{o}},\,\,{{35}^{o}}\]
B) \[{{65}^{o}},\,\,{{80}^{o}},\,\,{{35}^{o}}\]
C) \[{{35}^{o}},\,\,{{80}^{o}},\,\,{{65}^{o}}\]
D) \[{{80}^{o}},\,\,{{35}^{o}},\,\,{{65}^{o}}\]
Correct Answer: A
Solution :
\[A+B+C={{180}^{o}}\] \[\Rightarrow \]\[({{15}^{o}}+B)+B+(B-{{30}^{o}})={{180}^{o}}\] \[\Rightarrow \]\[A={{80}^{o}},C={{35}^{o}}\]You need to login to perform this action.
