Answer 1

sin 45

Explanation:

Answer 2

sin 45° =
`(1)/(√(2) )`

Explanation:

Sin function is a trigonometric function.

Sin value of any angle is defined as a ratio of perpendicular to its hypotenuse.

Now, By definition in a ΔABC, Sin A =
`(P)/(H)`

Now, the value of is a constant.

and the value of sin 45° =
`(1)/(√(2) )`
