It is 2*360/(2+4+4+5) = 2*360/15 = 48 degrees.

To find the measure of the smallest angle, we need to assign values to the angles. Let's say the angles are 2x, 4x, 4x, and 5x. Since the sum of the angles in a quadrilateral is 360 degrees, we can set up the equation 2x + 4x + 4x + 5x = 360. Simplifying, we get 15x = 360, so x = 24. Therefore, the smallest angle is 2x = 2 * 24 = 48 degrees.
