The measures of the angles in a quadrilateral are represented by x, 2x, 3x, and 3x.

Write an equation that would allow you to solve for the value of x.

Solve for the value of x

X + 2X + 3X + 3X = 360.

9X = 360,
X = 360 / 9 = 40 Deg.

To write an equation that allows you to solve for the value of x, we need to use the fact that the measures of the angles in a quadrilateral sum up to 360 degrees.

The sum of the angles in a quadrilateral is given by the equation:

x + 2x + 3x + 3x = 360

To solve for the value of x, we combine like terms and solve the resulting equation:

9x = 360

Dividing both sides by 9, we have:

x = 40

Therefore, the value of x is 40.
