Master finding the missing angle measure using supplementary angles

This video tutorial explains how to solve for X using supplementary angles, which are angles that add up to 180 degrees. The instructor demonstrates solving equations with both horizontal and vertical lines, combining like terms, and understanding intersecting lines. The tutorial includes multiple examples, emphasizing the importance of verifying solutions to ensure accuracy.

What is the sum of supplementary angles?

• 90 degrees

• 270 degrees

• 360 degrees

• 180 degrees

If one angle is 125 degrees, what is the measure of its supplementary angle?

• 55 degrees

• 65 degrees

• 75 degrees

• 85 degrees

In a vertical line, if 2X + X - 30 = 180, what is the value of X?

• 60 degrees

• 90 degrees

• 80 degrees

• 70 degrees

How do you combine like terms in the equation 3X + 2X = 180?

• 7X

• 4X

• 5X

• 6X

What is the value of X if 5X = 180?

• 30

• 36

• 40

• 45

In the equation 2X + 4X + 108 = 180, what is the first step to solve for X?

• Multiply both sides by 6

• Divide both sides by 6

• Add 108 to both sides

• Subtract 108 from both sides

If 14X - 2 = 180, what is the value of X?

• 14

• 13

• 12

• 15
