13. Jackie puts up a shelf in her room. The shelf is 2 m long, correct to the nearest 10 cm.
Jackie plans to use the shelf to store DVD cases.
Each DVD case is 2 cm wide, correct to the nearest mm.
(a)
Work out the maximum possible number of DVDs that could be stored on the shelf.

100 dvds

Step-by-step explanation:

2m = 200cm

200/2 = 100

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°
