The angles x - 10° and 190° - x are
a. interior angles on the same side of the transversal
b. making a linear pair
c. complementary
d. Supplementary
Solution:
Given, the angles are x - 10° and 190° - x.
We have to determine the nature of the angles.
Sum of angles = x - 10° + 190° - x
= -10° + 190°
= 180°
When the sum of the measures of two angles is 180°, the angles are called supplementary angles.
Therefore, the given angles are supplementary.
✦ Try This: The angles x - 10° and 100° - x are
Given, the angles are x - 10° and 190° - x.
We have to determine the nature of the angles.
Sum of angles = x - 10° + 100° - x
= -10° + 100°
= 90°
When the sum of the measures of two angles is 90°, the angles are called complementary angles
Therefore, the given angles are complementary
