The sum of the interior angle measures of a convex dodecagon. 2. Corrected_text: The measure of each interior angle of a regular 20-gon.
Added by Robert R.
Step 1
To find the sum of the interior angle measures of a convex dodecagon, we can use the formula: Sum of interior angles = (n-2) x 180 degrees where n is the number of sides of the polygon. For a dodecagon, n = 12, so we have: Sum of interior angles = (12-2) x 180 Show more…
