Quadrilateral

Question

The sum of two angles of quadrilateral is 180 degree.find sum of remaining angles.

Answer 1

Given,
The sum of the two angles of a quadrilateral is 180°

Let the sum of the remaining two angles be x+y.

Concept used:
The sum of the angles of a quadrilateral is given
=360°

Apply the above concept, we get
180°+(x+y)° =360° 
 (x+y)°=360° −180°
 (x+y)° =180°
