x=12 degree

Step-by-step explanation:

and all angles are by puttin 12

Answer 2

Answer:

angle 1= 36

angle 2= 60

angle 3= 108

angle 4= 156

Step-by-step explanation:

3x + 5x + 9x + 13x = 360

30x = 360

x = 360÷30

x = 12

angle 1= 3 × x

= 3 × 12

= 36

angle 2= 5 × x

= 5 × 12

= 60

angle 3= 9 × x

= 9 × 12

= 108

angle 4= 13 × x

= 13 × 12

= 156
