Which relationships describe the angle pair x and 71º Select each correct answer complementary angles adjacent angles vertical angles supplementary angles

Answer :

The relationships that describe the angle pair x° and 71º can be vertical angles, supplementary angles, or complementary angles.

The relationships that describe the angle pair x° and 71º are:

  1. Vertical angles: Vertical angles are angles formed by two intersecting lines, and they are congruent. Therefore, x° and 71º could be vertical angles.
  2. Supplementary angles: Supplementary angles are two angles whose measures add up to 180 degrees. If x° and 71º are supplementary angles, then x + 71 = 180.
  3. Complementary angles: Complementary angles are two angles whose measures add up to 90 degrees. If x° and 71º are complementary, then x + 71 = 90.

Answer:

complementary angles

Step-by-step explanation:

By the angle addition postulate, x + 71 = 90.

Then, by the definition of complementary angles, that makes the angles x and 71 complementary angles.
