# Two sides of a rhombus measure 5x and 2x + 18. Find x.

A rhombus is a quadrilateral in which all the four sides are equal.

It is given that 2 sides of a rhombus have lengths 5x and 2x + 18. We have to determine x.

As the sides have the same length equate 5x and 2x + 18 and solve for x.

5x = 2x + 18

=> 5x - 2x = 18

=> 3x = 18

=> x = 18/3

=> x = 6

**The value of x = 6**

The length of the sides of a rhombus are 5x and 2x + 18. As the length of all sides of a rhombus are the same, to determine x equate the two terms and solve the resulting equation for x.

5x = 2x + 18

Subtract 2x from both the sides

5x - 2x = 2x - 2x + 18

3x = 18

Divide the two sides by 3

x = 6

The value of x is 6.
