Question

Triangles PQR and XYZ are equilateral triangles. The sides of PQR are

5 inches long. One side of XYZ is (2x - 3) inches. What value of x
makes the triangles congruent?

Answer 1

x = 4

Explanation:

2x - 3 = 5 Add 3 to each side

2x - 3 + 3 = 5 + 3

2x = 8 Divide both sides by 2

`(2x)/(2)` =
`(8)/(2)`

x = 4
