Question

Sides are added to a convex polygon so that the sum of its interior angle measures is increased by 540 degrees. How many sides are added to the polygon?

Answer 1

A convex polygon has 5 sides.

Answer 2

Formula for sum of interior angles.\[180(n-2)=interior sum\]
Use it to find the interior sum of a polygon with 5 sides.

Answer 3

\[180(n-2)=540\]
Sorry find n for me.
\[180n-360=540\]
