Question

Calcule o valor de X nos triângulos

Answer 1

Resposta:

a) X + 90 + 35 = 180

X + 125= 180

X = 180 - 125

X = 55

b) 50 + 30 + X = 180

80 + X = 180

X = 180 - 80

X = 100

c) 50 + 65 + X = 180

115 + X = 180

X = 180 - 115

X = 65

d) 6X + 4X + 2X = 180

12X = 180

X = 180

12

X= 15

6.15= 90

4.15= 60

2.15= 30

2)

a) 50 + 70 + 110 = 360

X + 230 = 360

X= 360 - 230

X= 130

b) 90 + 90 + 4X + 2X = 360

180 + 6X = 360

6X = 360 - 180

6X = 180

X = 180

6

X= 30
