Practice

Using the diagram, answer the following questions.


  • ∠ABD and ∠DBC are supplementary angles. If the m∠ABD = 2x + 104 , and m∠DBC = -9x + 104 , solve for x.
  • State the two angle measures.

  • ∠ABD and ∠DBC are complementary angles. If the m∠ABD = 2x + 104 , and m∠DBC = -9x + 104 , solve for x.
    x = 4
  • State the two angle measures.
    m∠ABD =112 and m∠DBC = 68
