The angle which makes a linear pair with an angle of 61° is of (a) 2

1.	The angle which makes a linear pair with an angle of 61° is of (a) 29° (b) 61° (c) 122° (d) 119°
Answer» (d) 119^o 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^o. Let the measure of other angle be x^o. Then, x + 61^o = 180^o x = 180^o – 61^o x = 119^o

Answer»

(d) 119^o

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^o.

Let the measure of other angle be x^o.

Then,

x + 61^o = 180^o

x = 180^o – 61^o

x = 119^o
