If angle ∠ABD is 67°. What is ∠DBC?

• 180°
• 90°
• 67°
• 23°

If ∠COB is 124°, then what is ∠BOD and how are they related?

• 56°, they are supplementary angles
• 90°, they are complementary angles
• 124°, they are vertical angles

What is the measure of b?

Since the angles have a complementary relationship, use the equation 5x + 65 = 90 to solve for x.

• x = 25

• x = 5

• x = 8

• x = 12

Since the angles have a supplementary relationship, use the equation 3x + 123 = 180 to solve for x.

• x = 15

• x = 16

• x = 28

• x = 19
