An isosceles triangle has a perimeter of 28.12 centimeters. The length of the longest side is 13.08 centimeters. What could be the length of one of the other sides of the triangle?
A. 3.92 centimeters
B. 7.52 centimeters
C. 11.26 centimeters
D. 15.04 centimeters

7.52 cm

Step-by-step explanation:

If we subtract the longest side from the whole perimeter, we get 28.12 - 13.08 = 15.04.

So the other two sides must be equal, since the triangle is isosceles.

That means 15.04 must be divided evenly betweem two sides.

15.04/2 = 7.52

So the 3 sides are 13.08 cm, 7.52 cm, and 7.52 cm.

You check the answer by adding all 3 sides together and we do indeed get the perimeter, 28.12 cm.

26?

step-by-step explanation:

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
