An isosceles trapezoid has a perimeter of 49 miles. its shorter base measures 12 miles and its longer base measures 23 miles. the two remaining sides have the same length; what is that length?

The perimeter is 49 miles, which means that all the sides added up must equal 49. Let's write and equation with the information given, where x is the magnitude of the two sides:

Simplify this a little bit to get x on one side:

Divide by 2 on both sides, and your answer is:

Therefore, the length of the two sides of the trapezoid are both 7 miles.

answer: it is 8

step-by-step explanation:

you know why its 8
