Answer:
20
Step-by-step explanation:
This is a right triangle
a² + b² = c²
16² + 12² = x²
256 + 144 = x²
400 = x²
take the square root of both sides
x = 20
Well there aint no whole number for this thee are 85 in each bag, so what is 680 divide 12 that is 56.6 like i said not a whole number so round to nearest.
