Question

The perimeter of a triangle is 27.1 feet. The sides of the triangle measure 9.8feet, 10.9 feet, and x feet. Write an equation to find the missing side. * 9.8 + 10.9 = 27.127.1-9.8 - 10.9 = xX + 9.8 + 10.9 = 27.1X - 27.1 = 9.8 + 10.9Which one? Please help!

Answer 1

For this problem we know that the perimeter of a triangle is given by the sum of the sides and we can set up the following equation:

9.8 + 10.9 + x = 27.1

And the best answer would be:

X + 9.8 + 10.9 = 27.1
