Find the least whole number N so that 2020 + N is exactly divisible by 11.

Step-by-step explanation:

Given :

Whole Number = N

Number = 2020 + N

Solution :

Now through observtion,

 ----- (1)

We took 184 because when we multiply 184 by 11 we get the nearest number to 2020

So from equation (1),

2020 + N ≡ 0 (mod 11)

N ≡ -2020 (mod 11)

Notice that 2020 = 183 • 11 + 7, so

N ≡ -(183 • 11 + 7) (mod 11)

N ≡ -7 (mod 11)

N ≡ 4 (mod 11)

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
