explanation ( a line is equal to 180° )
2x+204=180
2x=-24
x= -12

check:
-12 + 132 = 120
-12 + 72 = 60

60 + 120 = 180

hope this helps (:

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
