Question

ASSERTION-REASON

The following questions consist of two statements—Assertion(A) and Reason (R). Answer these questions selecting the appropriate option given below.

(a) Both A and R are true and R is the correct explanation for A.
(b) Both A and R is not the correct explanation for A.
(c) A is true but R is false.
(d) A is false and R is true.

1. ASSERTION (A) : sin² 67° + cos² 67° = 1
REASON (R) : For any value of theta,
sin² theta + cos² theta= 1.


2. ASSERTION (A) : If cos A + cos² A = 1
then sin² A + sin⁴ A =
2.
REASON (R) : 1 - sin² A = cos² A, for any
value of A.


3. ASSERTION (A) : In a right angled
triangle, if tan theta =
¾ then sin theta = ⅗.
REASON (R) : sin 60° = ½​

Answer 1

Step-by-step explanation:

. ASSERTION (A) : sin² 67° + cos² 67° = 1

REASON (R) : For any value of theta,

sin² theta + cos² theta= 1.

Answer (a) Both A and R are true and R is the correct explanation for A.

ASSERTION (A) : If cos A + cos² A = 1

then sin² A + sin⁴ A =

cos A +cos^2 B = 1

cos A= 1- cos A^2

cos A= sin ^2

then cos ^2 = sin ^4A

sin^2 A +sin ^4 A =

sinA ^2 A + cos ^2 A = 1

answer

Both A and R are true and R is the correct explanation for A.

3. ASSERTION (A) : In a right angled

triangle, if tan theta =

¾ then sin theta = ⅗.

REASON (R) : sin 60° = ½

answer Both A and R is not the correct explanation for A.
