To find the measure of the unknown angle in a quadrilateral, you need to know that the sum of all angles in a quadrilateral is 360 degrees.

Step 1: Add up the known angles.
90.2° + 50.2° + 157.8° = 298.2°

Step 2: Subtract the sum of the known angles from 360° to find the measure of the unknown angle.
360° - 298.2° = 61.8°

So, the measure of the unknown angle is 61.8°.
