Answer:

Therefore, the value of x is 70 (B.)

Step-by-step explanation:

As the figure shown, we can see it's a Triangle and Triangle sums up to 180°. Therefore,

  • [tex] 38 + x + 2 + x = 180 [/tex]

Group like terms

  • [tex] x + x + 38 + 2 = 180 [/tex]
  • [tex] 2x + 38 + 2 = 180 [/tex]
  • [tex] 2x + 40 = 180 [/tex]
  • [tex] 2x + 40 - 40 = 180 - 40 [/tex]
  • [tex] 2x = 140 [/tex]
  • [tex] \frac{2x}{2} = \frac{140}{2} [/tex]
  • [tex] x = 70 [/tex]

Therefore, the value of x is 70 (B.)
