Pearl solved a system of two linear equations. In the final step, she found herself writing "O = 6." Pearl thought she had done something wrong, but she had not. Explain what occurred here and how the graphs of the two equations are related.

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°
