A section of a highway is constructed with a 11% grade. What angle does the highway make with a horizontal line? Round to the nearest hundredth of a degree. m∠A ≈ 84.81°
m∠A ≈ 83.72°
m∠A ≈ 6.28°
m∠A ≈ 5.19°

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

the answer is d on edge
