• Determining the value of y and angles A and B

What is the sum of adjacent angles formed by intersecting lines?

• 270 degrees

• 360 degrees

• 180 degrees

• 90 degrees

Which equation represents the relationship between 78 degrees and the expression 5y + 2?

• 78 + 5y + 2 = 90

• 78 + 5y + 2 = 180

• 78 + 5y + 2 = 360

• 78 + 5y + 2 = 270

What is the first step in solving the equation 5y + 80 = 180?

• Subtract 80 from both sides

• Add 80 to both sides

• Divide both sides by 5

• Multiply both sides by 5

What is the value of y after solving the equation?

• 20

• 15

• 10

How do you calculate the angle measure using the value of y?

• Multiply y by 10 and add 5

• Multiply y by 5 and add 2

• Multiply y by 5 and subtract 2

• Multiply y by 2 and add 5

What is the measure of the angle calculated using y = 20?

• 106 degrees

• 104 degrees

• 102 degrees

• 100 degrees

What are vertical angles?

• Angles that are on opposite sides and are equal

• Angles that are on the same side

• Angles that form a straight line

• Angles that are adjacent to each other

If angle A is 102 degrees, what is the measure of the vertical angle opposite to it?

• 180 degrees

• 102 degrees

• 90 degrees

• 78 degrees

What is the measure of angle B if the angle opposite to it is 78 degrees?

• 78 degrees

• 90 degrees

• 102 degrees
