Answer:
3x=3 x 12=36
5x=5 x 12=60
9x=9 x 12=108
13x=13 x 12=156
Step-by-step explanation:
Let angles 3:5:9:13 be 3x,5x,9x,13x
where x is any number
we know that ,
sum of angles of a quadrilateral is 360
3x+5x+9x+13x=360
30x=360
x=360/30
therefore, x=12
hence the angles are
3x=3 x 12=36
5x=5 x 12=60
9x=9 x 12=108
13x=13 x 12=156
