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
Being a quadrilateral, the sum of all four angles is 360o.Opposite angles of a parallelogram are equal.Adjacent angles of a parallelogram are supplementary, that is add to 180o.Given one angle of a parallelogram, the other 3 angles can be calculated:the opposite angle is the same;the other two angles are the same as each other and are 180o - the_given_angle

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.
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.
Subtract the two known angles from 180 degrees will give you the missing angle
360 degrees
