he table shows the number of songs that were downloaded and the total cost for buying the songs. What is the rate of change for the function in the table? 2 songs for $1 $2 per song 4 songs for $1 $4 per song

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°
