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)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/v9d7747jj07lwhflbupy0dbqvstrg5part.png)
Now, the value of is a constant.
and the value of sin 45° =
![(1)/(√(2) )](https://img.qammunity.org/2020/formulas/mathematics/middle-school/5bxvhlb2iww466wd3lsgzyfb811pdr610z.png)
