Answer:

Step-by-step explanation:

The inequality says greater than or equal to 8, which means the first two are automatically ruled out because they are both less than/equal to.

Then look at C and D, D starts at 3 and C starts at 8 so the answer should be C

Cos(theta)= -.9041, 180degress< theta <270degress

AVprozaik [17]

Answer:

$\theta=205.298^o$

Step-by-step explanation:

We know

$cos\theta=-.9041$

in the third quadrant $180^o$

We use a scientific calculator to find the inverse cosine of -0.9041 to find

$\theta=154.702^o$

Since this angle is not in the required quadrant we must find the other angle who has the same cosine. The required angle is equidistant from the found value from the 180 degrees angle, so our solution is

$\theta=180^o+(180^o-154.702)=205.298^o$

What is the measure of an interior angle in a regular octagon?

andrew11 [14]

To find the interior angle of any regular polygon you can use the formula $\frac{(n-2)*180}{n}$ where n is the number of sides
So, $\frac{(8-2)*180}{8} =135$
The measure of an interior angle in a regular octagon is 135
