The answer is 2x<span>^2
Because everything on the right of the minus sign will turn negative

138° + w° = 180° (sum of angle on a straight line)
w° = 180° - 138°
w = 42
19° + x° + w° = 90°
sub. in w=42,
19° + x° + 42° = 90°
x° = 90° - 19° - 42°
x° = 29°
x = 29
Okay so this problem basically is saying if the value is 90000 and per every 1000 she has to pay 31$ in tax
So first divide $90,000 by $1,000 you should get 90
Now you can do 90 times $31 to find how much tax she will have to pay which equals $2,790 tax total
Im not sure wym but i think the answer is 20
