Answer: x = 
Step-by-step explanation:
The exterior angle of a triangle = sum of the opposite interior angle.
The interior angles given are :
and 
Which are opposite to x + 72
Therefore :
x + 72 =
+ 
x + 72 = 
x =
- 
x = 
Answer:
18 snack packs
Step-by-step explanation:
2 1/4 = 9/4 = 18 / 8
18/8 divided by 1/8 = 18
Maybe 3 or 6 or 8, the formula for the volume of a rectangular prism = a * b * c. A<span>, B, C are the length, width, and height. and 3*6*8=144</span>
558 gallons are used when the car has been driven 18 miles.
<u>Step-by-step explanation:</u>
<u>From the given data, it can be determined that :</u>
- The number of gallons for 2 miles = 62 gallons
- The number of gallons for 4 miles = 124 gallons
- The number of gallons for 10 miles = 310 gallons
Let, the number of gallons for 18 miles = 'x' gallons
<u>To find x :</u>
compare the given data with the unknown data,
62 gallons / 2 miles = x gallons / 18 miles
keep x alone on one side,
x = (62×18) / 2
x = 31×18
x = 558 gallons
Therefore, 558 gallons are used to drive 18 miles.
5 by the 3 is 5X5X5 = 125
125-4 = 121
answer = 121
