Math help? explain please.?
The measure of the smallest in a triangle can never be:
a. 1/2 degrees
b. 10

The measure of the smallest [angle] in a triangle can never be:
d 61
The angles in a triangle measure 180. If one angle measures, 61, then there are 119 degrees to distribute among 2 other angles, or an average of 59.5 angle. Therefore, one angle HAS to be smaller than 61, and therefore 61 CANNOT be the smallest angle.
A hexagon has 6 sides. Use this formula
Sum of interior angles = 180(n-2)
=720/6
=120

8 is an answer to last one
pretend that the cube is 1 x 1 x 1 and still requires 1 liter of paint
if you double it, it becomes 2 x 2 x 2 or 8 cubic units
in the first one, it was 1 liter/cubic unit
so 1 x 8 = 8 liters
cheers
