Which of the following values of n will result in a true statement when substituted into the given equation? 4n + 9 = 1

A. n = -2
B. n = 2
C. n = 3
D. n = 4

A

Step-by-step explanation:

If we subtract both sides by 9, we have 4n = -8. Dividing by 4, we have n = -2. So the answer is A

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°
