Select the equation that correctly models the angle relationship shown in the diagram.

• 5x + 7x - 20 = 180

• 5x + 7x - 20 = 90

• 5x = 7x - 20

• 7x - 20 - 5x = 45

CCSS.7.G.B.5

Select the equation that correctly models the angle relationship shown in the diagram.

• 2x - 30 = x + 60

• 2x + x = 60 - 30

• 2x - 30 + x + 60 = 90

• 2x - 30 + x + 60 = 180

Select the equation that correctly models the angle relationship shown in the diagram.

• x + 3 + x - 1 + x + 1 = 90

• x + 3 = x - 1 + x + 1

• x + x + x = 3 - 1 + 1

• x + 3 + x - 1 + x + 1 = 180

Select the equation that correctly models the angle relationship shown in the diagram.

• 2x - 17 = 63

• y + 23 = 2x - 17

• y + 23 = 63

• 2x - 17 = y + 23 + 63
