The sum of the angle measures of a polygon with n sides is 1260. find n.

Murrr4er [49]

Knowing the interior angle sum formula is;

180x(n-2)

180x(n-2)=1260 (solve for n here)
180n-360=1260
180n=1260+360
180n=1620
n=1620/180
n=9

Therefore, this polygon has 9 sides.

Hope I helped :)

Koalas absorb only 25% of the fiber they eat. A koala absorbed 10.5 ounces of fiber in one day. How many ounces of fiber did he

sweet [91]

$\huge{\boxed{\text{42 ounces}}}$

25% is equal to $\frac{1}{4}$ , so multiplying it by 4 gets 100%. This means we can multiply 10.5 by 4 to get 100% of the fiber the koala ate that day.
