Question

Identify the linear pair of angles a) 48°, 112° b)84°, 96° c) 110°, 90° d) 100°, 90°​

Answer 1

Answer:

option B( 84,96)

Step-by-step explanation:

180°= 84+96

Answer 2

Given pair of angles :

   a) 48°, 112°

   b)84°, 96°

   c) 110°, 90°

   d) 100°, 90°​

Need to do : Find the angles which are linear pair.

Must know : Linear pair are angles whose some is 180° and they lie on a straight line.

Solution :

For 1st Pair -

→ 48° + 112° = 180°

→ 160° ≠ 180°

• Hence, it is not a linear pair

For 2nd Pair -

→ 84° + 96° = 180°

→ 180° = 180°

• Hence, it is a linear pair.

For 3rd Pair -

→ 110° + 90° = 180°

→ 200° ≠ 180°

• Hence, it is not a linear pair.

For 4th Pair -

→ 100° + 90° = 180°

→ 190° ≠ 180°

• Hence, it is not a linear pair

       ________

Henceforth, the pair of 84°, 96° is a linear pair [ Option 'b' ]
