A) 5
B) 3
C) 9
D) 2
Correct Answer: C
Solution :
\[\frac{{{\tan }^{2}}60{}^\circ +4{{\sin }^{2}}45{}^\circ +{{\sec }^{2}}30{}^\circ +5{{\cos }^{2}}90{}^\circ }{\cos ec30{}^\circ +\sec 60{}^\circ -\cot 30{}^\circ }\] \[=\frac{({{\sqrt{3)}}^{2}}+4{{\left( \frac{4}{\sqrt{2}} \right)}^{2}}+3{{\left( \frac{2}{\sqrt{3}} \right)}^{2}}+5(0)}{2+2-{{(\sqrt{3})}^{2}}}\] \[=\frac{3+2+4+0}{1}=9\]You need to login to perform this action.
