Find the measure of each angle of a regular polygon with 8 sides

mr Goodwill [35]

$\bf \textit{sum of all interior angles in a polygon}\\\\
\stackrel{sum}{\theta n}=180(n-2)\quad 
\begin{cases}
\theta =angle~in\\
\qquad degrees\\
n=\textit{number of sides}\\
---------\\
n=8
\end{cases}\implies \theta 8=180(8-2)
\\\\\\
\theta 8=180(6)\implies \theta 8=1080\implies \theta =\cfrac{1080}{8}\implies \theta =135$

What is the answer to this problem?

salantis [7]

We must first Isolate the Variable by removing factors that don't contain the variable:

2(x + 7) < 12
2x + 14 < 12
2x + 14 - 14 < 12 - 14
2x < -2
2x / 2 < -2/2
x < -1

Hope this helps!

Two thirds of a number is no more than -10

Aliun [14]

Let x be the number in the problem. When it states that x is "no more than -10", it means than it is less than or equal to -10. So, we have

$\frac{2}{3}$ x≤-10

In order to cancel out the $\frac{2}{3}$ on the left and isolate x, we multiply both sides by $\frac{3}{2}$ (since $\frac{3}{2}$ · $\frac{2}{3}$ =1). Thus, we have

x≤-10· $\frac{3}{2}$ =-15

Therefore, x≤-15
