Answer 2

I assume you meant "cos 80.0°."

To calculate the cosine of 80.0 degrees, we first need to ensure that the angle is in radians. The formula to convert from degrees to radians is:

radians = degrees * (π / 180)

Let's plug in the value for 80.0 degrees:

radians = 80.0° * (π / 180) ≈ 1.3962634 radians

Now, we can calculate the cosine of this angle:

cos(80.0°) ≈ cos(1.3962634) ≈ 0.17364818

So, cos 80.0° is approximately 0.1736.
