yawa3891 [41]

Megabyte is equal to 1 million bytes, while kilobyte is equal to 1000 bytes.

Divide 1,000,000 with 1,000

1000000/1000 = 1000

There are 1000 kilobytes in 1 megabyte.

The answer would be $42.4. $50 minus $10 is $40. Multiply that by 106% because of tax, and you get $42.4.

Answer:

x° = 99°

Step-by-step explanation:

The polygon is a hexagon and the sum of its internal angles is:

$180(n-2)=180(6-2)=180(4)=720^{0}$

subtract the 5 known angles:

$x^{0} =720-145-164-59-132-121=99^{0}$
