Vertical and straight angles solve for the measure of an two angles with two variables

The video tutorial explains how to solve a problem involving angles and variables. It covers the concepts of supplementary and vertical angles, demonstrating how to use these relationships to solve for unknown variables. The instructor guides through the process of substituting variables and combining like terms to find the solution, emphasizing the importance of understanding angle relationships.

What do we call two angles that add up to a straight line?

• Complementary angles

• Adjacent angles

• Vertical angles

• Supplementary angles

When two angles intersect, what is the relationship between the opposite angles?

• They are adjacent

• They are supplementary

• They are equal

• They are complementary

If Y is equal to 2X, what is the expression for the angle in terms of X?

• 2X + 5

• Y + X + 5

• 2X + X + 5

• X + 5

What is the first step in solving the equation 5X + 5 = 180?

• Add 5 to both sides

• Multiply both sides by 5

• Divide both sides by 5

• Subtract 5 from both sides

If X equals 35, what is the value of Y given Y = 2X?

• 105

• 70

• 35

• 140
