What is the measure of the smaller of the two supplementary angles if the measure if the measure of one angle is one fourth the measure of the other angle?

The easiest way (for me) to solve this type of question is to put it into an equation in terms of x.
Since one angle is 1/4 the size of the other, the two angles would be x and 1/4x, or 4x and x (I suggest using 4x and x).
Since the angles are supplementary, their sum is 180 degrees.
4x+x=180
5x=180
x=36 degrees

If a trapezoid has a one hundred degree angle and a sixty-five degree angle and a seventy-five degree angle what is the measure of the fourth angle?
This is not a trapezoid. For all trapezoids (in plane Geometry), the two sets of side angles must be supplementary, or add to 180. No two angles given are supplementary.
