Answer:

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

iii. Cost of 24 chairs= Rs.9255.6= Rs.385.65
