Question

Determine o valor das icognitas abaixo

Answer 1

Resposta:

a) x + 70 + 80 = 180

x + 150 = 180

x = 180 - 150

x = 30

b) y + 55 + 90 = 180

y + 145 = 180

y = 180 - 145

y = 35

c) x + 120 = 180

x = 180 - 120

x = 60

y + 50 = 120

y = 120 - 50

y = 70

d) x + x + 100 = 180

2x = 180 - 100

2x = 80

x = 80/2

x = 40

e) x + 90 + 90 + 130 = 360

x = 360 - 180 - 130

x = 360 - 310

x = 50
