What is the measure of an interior angle of a regular three-sided polygon?

noname [10]

The formula to find the measure of an interior angle is $(n - 2) * 180/n$ , where $n$ represents the number of sides in the polygon. In this problem, $n$ would represent $3$ .

Let's plug in the value for $n$
$(3 - 2) * 180/3$
Let's simplify that.
$=60$

Now we know that the <span>measure of an interior angle of a regular three-sided polygon is 60</span>°. Your answer would be B!

Let me know if you have any questions regarding this problem!
Thanks!
