3-4: TEKS Practice

  • 1. Which of the following is a correct drawing of an adjacent supplement of the figure? Select all that apply.

    An angle measuring 114°.

    • A.

      Adjacent angles measuring 114° and 66° form an angle greater than 180°.

    • B.

      Adjacent angles measuring 114° and 66° form an angle greater than 180°.

    • C.

      Adjacent angles measuring 114° and 66° form an angle greater than 180°.

  • 2. Find the supplementary angle of 128.9°.

  • 3. Find the value of x using the measures of the two given adjacent supplementary angles.

    Supplementary angles measuring 54° and 3x°.

  • 4. If ∠ A and ∠ B are supplementary angles and ∠ A is three times as large as ∠ B, find the measures of ∠ A and ∠ B.

  • 5.

    • a. Writing Solve for x if the angles are adjacent supplementary angles.

    • b. Show how to check that your value of x is correct.

      Supplementary angles measuring 35° and 5x°.

  • 6. Error Analysis In the figure, ∠ EOG is a straight angle. Charlie incorrectly says the measure of ∠ FOG is 26°.

    Adjacent angles EOF and FOG form angle EOG. Angle EOF measures 64°.

    • a. What is the measure of ∠ FOG?

    • b. What error might Charlie have made?

      • A. Charlie found the complement instead of the supplement.

      • B. Charlie found the supplement instead of the complement.

      • C. Charlie found the measure of ∠ EOF instead of ∠ FOG.
