9 sides
Method 1: Since the interior angle 140 degrees, the supplement of this is the exterior angle and equal to 40 degrees. Hence the number of sides is 360/40 = 9 sides.
Since 4 quarts equal 1 gallon, 2 gallons and 8 quarts. 1/2 of a gallon equals 2 quarts. When you add 8 and 2 you get 10 quarts. The answer is 10 quarts.
1/8= 0.125
.125*8= 1
Some fractions also equivalent are:
2/16, 4/32, 8/64
