If f(x, y,z)=(x^3+y^2+z)^4 find each of the following:
(1)fx(x, y,z)=? 2) fy(0,1,1)=? 3) fzz(x, y,z)=?

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°
