0.5 pts For the given functions f and g, find the indicated composition.
f(x) = 4x2 + 2x + 8, g(x) = 2x - 6
(gof)(x)
4x2 + 4x + 10
8x2 + 4x + 10
8x2 + 4x + 22
4x2 + 2x + 2

Whats your question?

Step-by-step explanation:

What do you need help with?

answer: do you still need this?

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°
