Question

Calcule o valor de X nos triangulos

70 + x + 30 = 180
3x + 2x + x = 180
5x + 60 + x = 180
3x + 3x+20 + 40 =180
pffvv geente é pra hj !!

Answer 1

70 + X + 30 = 180
X = 180 - 100
X = 80 graus

3x + 2x + X = 180
6x = 180
X = 180 / 6
X = 60 graus

5x + 60 + X = 180
5x + X = 180 - 60
6x = 120
X = 120 / 6
X = 20 graus

3x + 3x + 20 + 40 = 180
3x + 3x = 180 - 20 - 40
6x = 120
X = 120 / 6
X = 20 graus

Answer 2

70 + x + 30 = 180

x = 180 - 70 - 30

x = 180 - 100

x = 80

3x + 2x + x = 180

6x = 180

x = 180/6

x = 30

》》》》》》》》》》》》

5x + 60 + x = 180

5x + x = 180 -60

6x = 120

x = 120/6

x = 20

》》》》》》》》》》》》

3x + 3x+20 + 40 =180

3x + 3x = 180 - 20 - 40

6x = 180 - 60

6x = 120

x = 120/6

x = 20
