Answer:

μ = 0.169

ME = 0.051

Step-by-step explanation:

The confidence interval is:

CI = μ ± ME

So the mean is the middle of the confidence interval, and the margin of error is half the difference.

μ = (0.118 + 0.220) / 2 = 0.169

ME = (0.220 − 0.118) / 2 = 0.051

Find the exact value of tan 195 degrees

melamori03 [73]

Answer:

$tan(195\°)=tan(15\°)=0.267949192431123...$

Step-by-step explanation:

We know that

$tan(195\°)=tan(15\°)$ , because $195\° - 180\° = 15\°$ .

Now, angle 15° or 195° is not an important angle which can be solve by a given table like 30°, 45° or 60°. This means we have to use the calculator to find the more exact value, which is

$tan(195\°)=tan(15\°)=0.267949192431123...$
