उत्तर
The angle which makes a linear pair with an angle of 61° is of 119°.
Explanation:
A linear pair is a pair of adjacent angles whose non-common sides are opposite rays.
We know that, measure of sum of adjacent angles is equal to 180°.
Let the measure of other angle be x°.
Then,
x + 61° = 180°
x = 180° – 61°
x = 119°
