Find the sum of the angles of a 12 sided polygon

1 answer:

4 0

The formula for the sum of the interior angles of a polygon is equal to (n-2)*180. the polygon has 12sides, so the sum of the interior angles of the polygonis equal to (12-2)*180 = 10*180 = 1800 degrees.

2 of the dozen eggs in a cartoon are cracked about what percent of the carton is not cracked

pychu [463]

well, a carton has a dozen, namely 12 or the 100%, two were cracked.

if we know 12 is the 100%, what is 2 off of it in percentage?

$\bf \begin{array}{ccll}
amount&\%\\
\cline{1-2}
12&100\\
2&x
\end{array}\implies \cfrac{12}{2}=\cfrac{100}{x}\implies x=\cfrac{2\cdot 100}{12}\implies x=16.\overline{66}$

Answer:

$\displaystyle a=\frac{d}{.5*t^2}$

Step-by-step explanation:

Equation Solving

We are given the equation:

$d=.5*a*t^2$

It's required to solve it for a.

Swap sides to have the letter on the left side:

$.5*a*t^2=d$

Divide by $.5*t^2$ :

$\mathbf{\displaystyle a=\frac{d}{.5*t^2}}$

Answer:

5 degrees

Step-by-step explanation:

Corresponding angles in a transversal are congruent. This can be proved by using the alternate exterior angles theorem, which would make these two angles alternate interior angles. With this, we can form a new equation.
