Step-by-step explanation:

9.supplementary angle

10.60 degree angle

11.x+(x+20)=180 degree

2x + 20 = 180 degree

2x = 180 - 20

2x = 160

x = 160/2

x = 80 degree

check : 80 + (80+20)=180

80+100 = 180

180 = 180....it is confirmed

12. 7:2

7+2=9

then,

i) 7/9×90

= 70

ii) 2/9×90

= 20

70+20=90...then, they r complementary angles

13.5:4

5+4= 9

5/9× 180

=100

4/9× 180

= 80

100+80=180....then, it is confirmed that they r supplementary angles

HOPE IT HELPS!!!!
