  1. Answer:

    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

    Hope this helps!
