You can put this solution on YOUR website! the angles of a quadrilateral are in arithmetic progression whose commom difference is 10. find the angles
----
Let the angles be x, x+10, x+20, x+30
---
Equation:
sum = (4-2)*180 degrees
sum = 360
4x+60 = 360
4x = 300
x = 75 degrees
x+10 = 85 degrees
x+20 = 95 degrees
x+30 = 105 degrees
