y = 9  when  x = 4

Step-by-step explanation:

If  y  varies inversely as  x  then XXX x ⋅ y = c  for some constant  c  

Given  y = 12  when  x =3  XXX 3 ⋅ 12 =c

XXX ⇒ c = 36  

So XXX x ⋅ y = 36   and when  

x = 4  

XXX 4 *y = 36  

XXX ⇒ y = 9

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°
