First draw six of anything take out one
<h3>Angles sum up to:</h3><h3>( n - 2 ) × 180 = ( 5 - 2 ) × 180 = 3 × 180 = 540</h3>




equation has infinitely many solutions has the same number on both sides of the equal sign
-3x -21 + x + 5 = -20x -16
-2x -16 = -20x -16
so either you have -18x on the left or +18x in the right
10cm
5cm is shown above all u gotta do is multiply by two OR add 5+5 to get 10 cm.
