Answer
The statement is false.
Work Step by Step
Thus, the value of sin45 from the table is $\frac{1}{\sqrt{2}}$ and the value of $\cos {{45}^{0}}$ is $\frac{1}{\sqrt{2}}$, so by putting the values in the equation and adding them, we get the value $\sqrt{2}$, which is not equal to 1. Hence, the statement is false.
