Subtract 300 from 360.
The 4 interior angles of a quadrilateral add up to 360 degrees. 360-65-90-60 = 145 degrees which is the missing angle
There is no such thing as a regular trapezoid. REGULAR implies that all sides and all angles are equal. If that is the case, with a quadrilateral each angle would be 90 degrees, none would be 50.
The answer will depend on what the shape is!
you cant
If there is no length for the hypotenuse you have to use the Pythagorean Theorem. If there are two sides missing and a reference angle you could use Trigonometry.

There is no specific limitation on any one angle of an inscribed quadrilateral.
180 minus two known angle = missing angle. Use Pythagoras' theorem to find its missing side.
When you add all four sides of a quadrilateral(all parallelograms are quadrilateral), It must equal 360 degrees. So what you do is you add up the three angles that are given, them subtract that sum from 360.
Use a protractor.
Subtract the 3 known angles from 360 to find the 4th angle.
A quadrilateral has four angles. There is information on only three so there are infinitely many possible answers.
Share If each quadrilateral below is a rhombus, find the missing measures UV: 8 and WX=5?
If you are trying to find the missing angle of a triangle you do 180 degrees minus your two other angles. However if you are trying to find the missing angle of a quadrilaterals you do the same thing but with 360 degrees.
Subtract the two known angles from 180 degrees will give you the missing angle
