A) \[\frac{5}{13}\]
B) \[\frac{5}{12}\]
C) \[\frac{12}{13}\]
D) \[\frac{13}{12}\]
Correct Answer: C
Solution :
[c]\[A{{C}^{2}}=A{{B}^{2}}+B{{C}^{2}}\] |
\[\Rightarrow \,\,\,\,\,\,\,\,\,B{{C}^{2}}={{(13)}^{2}}-{{(5)}^{2}}=144\,\,\,\,\Rightarrow \,\,\,\,BC=12cm\] |
\[\therefore \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\sin A=\frac{12}{13}\] |
