Question

o Determine o valor de
Cada angulo

Answer 1

Resposta:

A) a = 60°/b=80/c=120 /d=100

B)a=90/b=100/c=80 /d=90

C) a= 110 /b=160/c= 70/d=90

Explicação passo-a-passo:

X + x + 20 + x + 40 + x + 60= 360

4x = 360 - 120

4x = 240

4x = 240/4

X = 60

B) 90 +90 + x + x x + 20=360

2x = 360 - 90 - 90 - 20

2x = 360 - 200

2x = 160

X = 160/2

X = 80

C)90 +x +50 + 2x - 30 + x - 20 = 360

4x = 360 - 50 + 20 + 30

4x = 410 - 50

4x = 360

X = 360 /4

X = 90
