First, find the sum of your given angles, 90, 90, and 130. You get 310. Now subtract that from 360 since all quadrilaterals have exactly 360 degrees. Your answer is 50 degrees.
50
Subtract the two known angles from 180 degrees will give you the missing angle
A quadrilateral has four angles. There is information on only three so there are infinitely many possible answers.
To find the measure of an angle, you need to know the size of the entire angle and the other angles within the angle. Then, you subtract the smaller, known angles from the entire, large angle and you should get the measure of the missing angle.
All the angles of a square are 90 degrees.
Subtract the (sum of the other three angles) 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
Subtract the 3 known angles from 360 to find the 4th angle.
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
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.
Subtract the two known angles from 180 degrees will give you the missing angle
A quadrilateral has 4 interior angles that add up to 360 degrees and to find the unknown 4th angle while knowing the other 3 angles simply add them up and subtract the sum from 360 to find the 4th angle
180 minus two known angles = unknown angle

All the angles of a square are 90 degrees.
well for any quadrilateral you would need 3 other angles, then you would add them up, and then subtract from the total you get out of 360(the number that all quadrilateral angles add up to).
Subtract the (sum of the other three angles) from 360.
