Answer:
4,000
Step-by-step explanation:
You go to the thousand number and see if the hundred number is higher than 5, if not then its stays the same.
( 'x' is not 144 .)
The supplement of an angle is (180 - x) .
The problem says that (2/3) of 'x' is equal to (180 - x) .
180 - x = 2/3 x
Multiply each side by 3 :
( Note: 3 x 180 = 540 .)
540 - 3x = 2x
Add 3x to each side:
540 = 5x
Divide each side by 5 :
<u>x = 108°</u> .
3x - 18 = 42
3x = 42 + 18
3x = 60
x = 60/3
x = 20
