Question

how would you set up an equation to find the value of x?
rewatch
5x - 0.2 = 4x - 1.3
5x - 0.2 = x + 3.2
4x - 1.3 = x + 3.2

Explanation:

Step1: Use the property of congruent sides in a triangle

In an isosceles triangle, two sides are equal. Here, the two equal - side expressions are \(4x - 1.3\) and \(x + 3.2\).

Step2: Set up the equation

Since the two sides \(4x-1.3\) and \(x + 3.2\) are equal, we can set up the equation \(4x-1.3=x + 3.2\).

Answer:

\(4x-1.3=x + 3.2\)
