The angles x and 90° - x are
a. supplementary
b. complementary
c. vertically opposite
d. making a linear pair
Solution:
Given, the angles are x and 90° - x
We have to determine the nature of the angles.
Sum of angles = x + 90° - x
= 90°
When the sum of the measures of two angles is 90°, the angles are called complementary angles.
Therefore, the given angles are complementary.
✦ Try This: Determine the angles x and 180°- x are supplementary or not.
Given, the angles are x and 180° - x.
We have to determine if the given angles are supplementary.
Sum of angles = x + 180° - x
= 180°
When the sum of the measures of two angles is 180°, the angles are called supplementary angles.
Therefore, the angles x and 180° - x are supplementary
