Question

Folosind figurile de mai jos,determina x:​

Answer 1

Răspuns:

Explicație pas cu pas:

AOD are 90 grade

30 + x + 25 = 90

x = 90 - 30 - 25 = 35 grade

_______________

EOH are 140 grade

x + 70 + x = 140

2x + 70 = 140

2x = 140 - 70 = 70

x = 70 : 2 = 35 grade

_______________

MTS are 180 grade

x + 20 + 2x + x = 180

4x = 180 - 20

4x = 160

x = 160 : 4 = 40 grade

Answer 2

Răspuns:

Explicație pas cu pas:

a).

30°+x+25°=90°

x=90-55

x=35°

b).

x+70°+x = 140°

2x = 140-70

2x = 70

x=35°

c).

 x+20° +2x + x = 180°

4x = 180-20

4x= 160

x= 40°
