Solve for your missing variable given two angles that are a linear pair

The video tutorial explains how to solve for a variable using angle relationships, specifically focusing on linear pairs. It introduces the concept of linear pairs, which are two angles that form a line and are supplementary. The tutorial demonstrates how to write and solve an equation using these angles, ultimately solving for the variable X. The process involves setting up the equation, simplifying it, and solving for the unknown variable. The tutorial concludes with a summary of the method used to solve for X using linear pair angles.

What is a linear pair of angles?

• Two angles that are complementary

• Two angles that form a line

• Two angles that are adjacent

• Two angles that are equal

What is the sum of the measures of a linear pair of angles?

• 90 degrees

• 180 degrees

• 360 degrees

• 45 degrees

Which equation represents the relationship between the angles in a linear pair?

• 8X + 2X = 360

• 8X - 10 + 2X = 180

• 8X - 2X = 45

• 8X + 10 + 2X = 90

What is the first step in solving the equation 8X - 10 + 2X = 180?

• Subtract 10 from both sides

• Add 10 to both sides

• Combine like terms

• Divide by 10

What is the value of X in the equation 10X = 190?

• 180

• 19

• 10

• 190
