Angle a is 132 degrees
5x-18=3x+42
2x-18=42
2x=60
x=30
then plug 30 in the equation for angle a
5*30-18
150-18
132
As far as I can see, it should be 5/10 is parrots which is simplified into 1/2 .
Hope this helps!

And for #4:
The answer is $131.63
Nathan earns 9.75 dollars in <u>one</u> hour, and you want to figure out how many he makes in <u>thirteen and a half</u> hours. To do this, just multiply 9.75 by 13.5.
9.75*13.5 is 131.625. However, money only goes to the hundredths place, which means there are only 2 decimal places. This means you should <u>round 131.625 to the hundredths place</u>, which makes 131.63.
