A) \[0\]
B) \[1\]
C) \[\frac{1}{\sqrt{2}}\]
D) \[\sqrt{2}\]
Correct Answer: D
Solution :
\[\sin A=\frac{1}{\sqrt{2}},\] \[\cos C=\cos 45{}^\circ =\frac{1}{\sqrt{2}}\] |
\[\therefore \,\,\,\,\,\,\,\,\sin A+\cos C=\frac{1}{\sqrt{2}}+\frac{1}{\sqrt{2}}=\frac{2}{\sqrt{2}}=\sqrt{2}\] |
So, option [d] is correct. |
