Firstly, add 2 to both sides of the equation: $\frac{3}{5}x^2=-3$

Next, multiply both sides by 5/3: $x^2=-5$

Next, square root both sides: $x= \pm \sqrt{-5}$

Lastly, factor out i (i = √-1) and <u>your answer will be $x= \pm \sqrt{5}i$ </u>

The measure of each exterior angle of a regular 30-gon is

dezoksy [38]

Answer:

12°

Step-by-step explanation:

So, for your 30-gon, the interior angles total up to (30-2) * 180 = 5040. Each interior angle is that total divided by the number of interior angles, or 5040/30 = 168º:

<u>The measure of each exterior angle is the total divided by the number of angles, or 360/30 = 12º.</u>

Ede4ka [16]

$\frac{\sqrt{-49}}{(7-2i)-(4+9i)}=\\
\frac{\sqrt{-1*7*7}}{3-11i}=\\
\frac{7i}{3-11i}*\frac{3+11i}{3+11i}=\\
\frac{(7i)*(3+11i)}{3^2-(11i)^2}=\\
\frac{21i+77i^2}{9+121}=\\
\frac{21i-77}{130}=\\
\frac{-77+21i}{130}$

so it is the last option
