To answer this question, we need to remember that the sum of the interior angles of a quadrilateral is equal to 360º (in fact, we can divide a quadrilateral into two triangles, and the sum of interior angles of a triangle is equal to 180º).
Then, we have that a = 14º and b = 22º, then we can state the next equation:

And now, we can solve the equation for x as follows:
1. Add the like terms as follows:


2. Subtract 36º from both sides of the equation:

3. Divide both sides by 8 as follows:

Therefore, the value for x = 40.5º
Then, we can find the values for the measure of angle A as follows:

The measure of angle B is

The measure of angle C is

The measure of angle D is
