Question

Assertion: If angles 'a' and 'b' form a linear pair of angles and a = 40°, then b = 150°. Reason: Sum of linear pair of angles is always 180°

Answer 1

Answer:

assertion it is not a linear angle because 190 angle reason is correct

Answer 2

Given : Assertion: If angles 'a' and 'b' form a linear pair of angles and a = 40°, then b = 150°.

Reason: Sum of linear pair of angles is always 180°

To Find : true / False

Solution:

Assertion: If angles 'a' and 'b' form a linear pair of angles and a = 40°, then b = 150°.

if two angles forms a linear pair the sum is always  180°

a + b = 180°

=> 40° + 150° = 180°

=> 190° = 180°

which is False

Hence Assertion is False

Sum of linear pair of angles is always 180°  is TRUE
