Question

Assertion(A) : An angle which is equal to its complement is 45
Reason(R) : When the sum of the measures of two angles is 180°, the angles are called supplementary angles
(a) Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A)
(b) Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A)
(c) Assertion (A) is true but reason (R) is false (d) Assertion (A) is false but reason (R) is true​

Answer 1

Step-by-step explanation:

Complementary angles - 90°

So If one angle is 45° then another angle will also be 45° , So assertion is true.

Also, when sum of two adjacent angles are 180° , it is supplementary angle.

So, reason is also correct

but they don't seem to match

therefore answer will be

(b) Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion.
