Questions & Step-by-Step Solutions

Two parallel lines are cut by a transversal, creating angles of 75° and x°. What is the value of x?
  • Step 1: Understand that two parallel lines cut by a transversal create pairs of angles.
  • Step 2: Identify the angles formed. In this case, we have one angle measuring 75° and another angle measuring x°.
  • Step 3: Recognize that the angles 75° and x° are supplementary, meaning they add up to 180°.
  • Step 4: Write the equation for supplementary angles: 75° + x° = 180°.
  • Step 5: To find x, subtract 75° from 180°: x = 180° - 75°.
  • Step 6: Calculate the result: x = 105°.
