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?

The value of x is 2.7 m.

Step-by-step explanation:

An isosceles triangle has two equal sides.

1) Write the equation based on the provided context

2.1 m + 2x = 7.5 m

2) Take away 2.1 m from each side of the equation

(2.1 m + 2 x) - 2.1 m = 7.5 m - 2.1 m

2x = 5.4 m

3) Isolate the variable x to find the x value.

x= 5.4 m/ 2

x= 2.7 m
