Question

In a quadrilateral, the angels are x°,(x+10)°,(x+20)°,(x+30)°.Find the angles.​

Answer 1

Required angles are -75,85,95,105

Since its a quadrilateral..

We know that sum of angles of quadrilateral are 360.

x+x+10+x+20+x+30=360

4x+60=360

x=75

Now put the value of X in the rest of the given angles
