Question

Directions : In the following Questions, A statement of Assertion (A) is followed by A statement of reason (R ). Mark the correct option as:

Assertion : ${\sin }^{2}59°+{\cos }^{2}59°$ = 1

Reason : For any value of , ${\sin }^2\theta +{\cos }^2\theta =1$

• A. Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
• B. Assertion (A) is false but reason (R) is true.
• C. Assertion (A) is true but reason (R) is false.
• D.
  Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).

Answer 1

The correct option is A Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).

We know that ${\sin }^2\theta +{\cos }^2\theta =1$
therefore ${\sin }^{2}59°+{\cos }^{2}59°$=1
