Answer:


\text{cos}(x)\approx 0.4495

Explanation:

We have been given that
\text{tan}(x)=1.98 and
\text{sin}(x)=0.89. We are asked to find
\text{cos}(x).


\text{tan}(x)=\frac{\text{sin}(x)}{\text{cos}(x)}


\text{cos}(x)=\frac{\text{sin}(x)}{\text{tan}(x)}

Upon substituting our given values, we will get:


\text{cos}(x)=(0.89)/(1.98)


\text{cos}(x)=0.449494949


\text{cos}(x)\approx 0.4495

Therefore, the value of
\text{cos}(x) is approximately 0.4495.
