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:
- Vertical angles: Vertical angles are angles formed by two intersecting lines, and they are congruent. Therefore, x° and 71º could be vertical angles.
- 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.
- 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.
