Question

os angulos de um triangulo sao expressos por 3x,x+10 e 2x+50 quais sao esses angulos
?

Answer 1

3x+x+10+2x+50 = 180
6x = 180-60
6x=120
x=120/6
x=20

3x = 3.20 = 60°
x+10 = 20+10 = 30°
2x+50 = 2.20+50 = 90°

Answer 2

ang1= 3x
ang2= x+10
ang3= 2x+50

3x+x+10+2x+50=180
6x+60=180
x=20

ang1=3.20=60
ang2=30
ang3=40+50=90
