Finding the Value of X and Y with Parallel Lines

The video tutorial explains how to find the measures of angles X and Y using properties of parallel lines. It covers the concept of corresponding angles to establish that angle Y equals 114 degrees. The tutorial then discusses supplementary angles and linear pairs to show that X + 12 and 114 add up to 180 degrees. Finally, it solves for X, concluding with remarks on grading.

What is the relationship between angle Y and the angle measuring 114 degrees?

• They are vertical angles.

• They are corresponding angles.

• They are supplementary angles.

• They are alternate interior angles.

Why do the angles X + 12 and 114 add up to 180 degrees?

• Because they are corresponding angles.

• Because they are alternate interior angles.

• Because they are vertical angles.

• Because they form a linear pair.

What is a linear pair?

• Two angles that are equal in measure.

• Two angles that are opposite each other.

• Two angles that form a line and share a vertex and a side.

• Two angles that are on the same side of a transversal.

What is the sum of angles in a linear pair?

• 270 degrees

• 180 degrees

• 360 degrees

• 90 degrees

What is the value of X in the equation X + 126 = 180?

• 180

• 114

• 126
