Answer:

c= 12.19

Step-by-step explanation:

Let's solve for c.

5.3(4x−2.3)=21.2x+c

Step 1: Flip the equation.

c+21.2x=21.2x−12.19

Step 2: Add -21.2x to both sides.

c+21.2x+−21.2x=21.2x−12.19+−21.2x

c=−12.19

Answer:

c=−12.19

The sum of seven interior angle measurements is an octagon equal 835°. What is the angle measurement of the eighth angle?

creativ13 [48]

$\bf \textit{sum of all interior angles in a polygon}\\\\ S=180(n-2)~~ \begin{cases} n=\textit{number of sides}\\[-0.5em] \hrulefill\\ n=8 \end{cases}\implies S=180(8-2) \\\\\\ S=180(6)\implies S=1080$

now, we know 7 of those angles are already 835°, so the last one must be 1080 - 835 = 245°.
