Question

The value of (sin 45° + cos 45°) is ______.

विकल्प

• `1/2`

• `1/sqrt(2)`

• `sqrt(2)`

• 2

Answer 1

The value of (sin 45° + cos 45°) is `underlinebb(sqrt(2))`.

Explanation:

sin 45° = cos 45° = `1/sqrt(2)` 

So, sin 45° + cos 45°

= `1/sqrt(2) + 1/sqrt(2)` 

= `2/sqrt(2)` 

= `sqrt(2)`
