Question

Determine o valor de x:

a) 2x 120°
b)3x 2x
c)2x 120°
d)2x + 40° x - 10°
e)x/2 65°
f)2x + 60° 4x- 40°​

Answer 1

Resposta:

A) 90 - 39 = 51, logo x = 51

B) 3x+2=90, 5x = 90, x = 18

C) 2x+120 = 180, 2x = 60, x = 30

D)2x+40+x-10 = 180,3x = 150, x = 50

E)x/2 = 65,x = 130

F)2x+60 = 4x-40, -2x = -100,2x = 100, x = 50
