Answer:

  • 90

Step-by-step explanation:

Angle 5 forms a linear pair with angle 8:

  • m∠5 + m∠8 = 180°

Substitute the values and solve for x:

  • x - 40 + 130 = 180
  • x + 90 = 180
  • x = 90

Answer:

  • The value of x is 90°.

Step-by-step explanation:

We know that:

  • ∠8 = 130°
  • ∠5 = x - 40
  • ∠5 + ∠8 = 180

Work:

  • 130 + (x - 40) = 180

Opening the brackets:

  • 130 + x - 40 = 180

Solving:

  • 90 + x = 180
  • => x = 180 - 90
  • => x = 90°

Hence, the value of x is 90°.

Hoped this helped.
