The isosceles triangle has a perimeter of 7.5 m. Which equation can be used to find the value of x if the shortest side, y, measures 2.1 m? 2 x minus 2.1 equals 7.5 4.2 plus y equals 7.5 y minus 4.2 equals 7.5 2.1 plus 2 x equals 7.5
The isosceles triangle has a perimeter of 7.5 m. Which equation can be used to find the value of x if the shortest side, y, measures 2.1 m?
x = (7.5 - 2.1) / 2
