Answer:

Step-by-step explanation:

The top left angle is 55 (alternate interior angles).

x + 100 + 55 = 180                     All triangles are made up of 180 degrees

x + 155 = 180                             Subtract 155 from both sides.

x = 180 - 155                              Combine

x = 25

Answer:

  • x = 25°

Step-by-step explanation:

  • => 55 + 100 + x = 180 [The '100' came into this equation because of vertically opposite angles.]
  • => 155 + x = 180
  • => x = 25°

Conclusion:

Hence, 'x = 25°' is the value of 'x'

Hoped this helped.
