Calculate m∠ABC.

• 45°

• 60°

• 105°

• 15°

Write an equation that correctly models the lengths shown.

• 2x + 20 + x + 21 = 9

• 2x + 20 + 9 = x + 21

• 9 + x + 21 = 2x + 20

• 2x + 20 - 9 = x + 21

Given that C is between A & B, which Segment Addition statement is correct?

• AC + AB = CB
• AC + CB = AB
• AB + BC = AC
• CA + CB = CA

Write an equation that correctly models the lengths shown.

• 3x + 2 + 6 = 2x - 2

• 2x - 2 + 6 = 3x + 2

• 6 - 3x - 2 = 2x - 2

• 2x + 2 + 3x + 2 = 6
