Given that p(-3) = 0, p(-1) = 0, and p(5) = 0, which expression could be p(x)? A) x3–x2–17x –15
B) x3+ x2–17x + 15
C) x3–3x2–13x + 15
D) x3–9x2+ 23x –15

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°
