X+(y+5)=19,deoarece 19-5=14,dar14=x+y,apoi dam valori lui x si y astfel incit suma lor sa fie egala cu 14 de exemplu x=6 si y=8.Demonstram (6+8)+5=19sau 6+(8+5)=19.gata:)

Answer:
x = 19; y = 19√3
Step-by-step explanation:
sin 30° = opp/hyp
sin 30° = x/38
x = 38 × sin 30°
x = 19
cos 30° = adj/hyp
cos 30° = y/38
y = 38 × cos 30°
y = 38 × √3/2
y = 19√3
