Answer:
x = 20 degrees
Step-by-step explanation:
All three angles added together form a straight line. A straight line is 180 degrees
3x+ 80 + 2x = 180
Combine like terms
5x+80 = 180
Subtract 80 from each side
5x+80-80 = 180-80
5x= 100
Divide each side by 5
5x/5 = 100/5
x = 20
<span><u><em>Answer:</em></u>
247,000
<u><em>Explanation:</em></u>
To round a number to the nearest thousand, we check the digit in the <u>hundreds position</u>:
1- If the digit is <u>less than 5</u>, then we round down. This means that we simply convert all digits after the thousands to zero and that's it
2- If the digit is <u>equal to or more than 5</u>, then we round up. This means that we add one to the thousands digit and then convert all digits after the thousands to zero.
In the given number 247039, the number in the hundreds position is 0. This means that we will <u>round down
</u>
Therefore, 246039 rounded to the nearest thousand would simply give 247000
