What term is used to describe a pair, or group, of angles that equal 180 degrees?

• Supplementary Angles
• Complementary Angles
• Vertical Angles
• Congruent Angles

What is the equation that could be used to solve for the missing angle measure?

• x + 64 = 90

• x = 64

• x + 64 = 180

• 90 - x = 64

• x = 118
• x = 108
• x = 28
• x = 58

Which equation below would you use to solve for x?

• 5x + x + 30 = 180

• 5x + x + 30 = 90

• 5x = x + 30

• 5x + 180 = x + 30

• 5x = x + 30 + 180

Solve for x.
