Find the domain of the function (f/g)(x), given f(x) = x² - 4x - 21 and g(x) = x² - 16.

{x | x ≠ -4 and x ≠ 4}
{x | x ≠ -3 and x ≠ 7}
{x | x ≠ 4}

i have tried photo math and such and can not get an answer

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°
