Question

Find the sum of the interior angle measuresof each polygon. Write equation and solveshowing ALL the work.42-gon

Answer 1

The sum of the interior angles for a 42-sided polygon is 7,200 degrees

Here, we want to find the sum of the interior angles for a 42-sided polygon

Mathematically, to evaluate this, we are to use the formula for the sum of the interior angles

We have this as;

`(n-2)*180`

n in this case is 42; we simply proceed to substitute 42 for n in the expression above

We have the result as;

`\begin{gathered} (42-2)*180 \\ =\text{ 40}*180\text{ = 7200} \end{gathered}`
