x=43
Step-by-step explanation:
A triangle contains 180
So
82+55+x=180
=>137+x=180
=>x=180-137
Therefore, x=43 (you can use therefore sign instead of therefore)
Answer: 36
Step-by-step explanation:
1.) You divide 180 by 20 to find out how many gallons their are
180÷20= 9
2.) Now you multiply the 9 by the cost of each gallon, which is $3.98
9×3.98= 35.82
3.) 35.82 is rounded to $36
