QUICK PLEASE Which expression is equivalent to 45−20s ? 25−s B 5(9−4s) C s(45−20) D 5s(9−4)

B. 5(9−4s)

Step-by-step explanation:

if you simplify that option it would be

45 - 20s

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°
