The required value is the angle theta and the value of the cosine of the angle is 0.9659

Given the expression of sine of an angle expressed as;

[tex]sin\theta = 0.2588[/tex]

For us to get the cosine of the angle, we need to get the value of theta first as shown:

[tex]\theta = sin^{-1}0.2588\\\theta = 14.99^0[/tex]

Next is to get the value of cos theta

[tex]cos \theta = cos 14.99 =0.9659[/tex]

The required value is the angle theta and the value of the cosine of the angle is 0.9659
