La diferencia entre la cuarta parte de un número y su siguiente, es igual a la quinta parte de dicho número disminuido en veinte unidades. ¿De
qué número se trata?

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°
