Answer 1

Answer:

D

Step-by-step explanation:

a+b will be 3 not 9 and reason is correct.

Answer 2

Answer:

Assertion statement is wrong but reason is correct statement.

Option (d) is correct.

Step-by-step explanation:

We have,

a = 2Sin²θ

b = 2Cos²θ + 1

Now,

a + b = (2Sin²) + (2Cos²θ + 1)

= 2Sin²θ + 2Cos²θ + 1

= 2(Sin²θ + Cos²θ) + 1

We know that,

Sin²θ + Cos²θ = 1

2(Sin²θ + Cos²θ) + 1

= 2(1) + 1

= 2 + 1

= 3

Hence,

Assertion is wrong statement

So, we don't need to check the reason

We can directly say that,

Assertion statement is wrong but reason is correct statement.

Option (d) is correct.

Hope it helped you and believing you understood it...All the best
