Step-by-step explanation:
i. Here l is parallel to m and t is a transversal
The sum of co interior angles is 180 degree.
(2x-8)+(3x-7)=180
2x+3x-8-7=180
5x=195
x=195/5= 39
(2x-8)degree= 70 degree
3x-7 degree= 110 degree
ii. 2.1*0.21*0.021= 21sq./1000= 441/1000=0.441
0.441*0.021= 441*21/1000000=0.009261
