LET 4:3:5:6 BE IN THE FORM 4x,3x,5x,6x
=4x +5x + 3x + 6x= 360
18x=360
x=130/9
x= USE CALACULATOR
=4x +5x + 3x + 6x= 360
18x=360
x=130/9

Let unknown no. be x
Ratio = 4:3:5:6
As we know that sum of all angles of a quadrilateral is 360 degree
4x + 3x + 5x + 6x = 360
18x = 360
x = 360/18
x = 20
Angles are 80,60,100,120
Verification
80+60+100+120=360
Hence verified
How is it ???
