The formula to find a hypotenuse is as follows: a^2 + b^2 = c^2 Write out your triangle, labeling one part as 18, and another as 80. Connect a line between the end points of each line, and give a letter to a value. For my example, I will use 18 as a and 80 as b. 18^2 + 80^2 = c^2 Solve this by squaring these numbers. 324 + 6400 = c^2 Add these numbers 6724 = c^2 Then, finally, deprive the square root from 6724 and c^2 82 = c Since c is you hypotenuse, 82 centimeters is your answer. This checks out because your hypotenuse must be the largest number of the three, and if not, you did something wrong. However, this all checks out, meaning your hypotenuse is 82 centimeters. Hope this helped!
2 liters equals approximately 68 ounces, which costs about 6 cents per 12 ounces (cost per ounce is too small to document). The cost per a twelve ounce can is about 0.29 cents. The can is the better deal.
