Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I have a question I have learn a bit about trigonometry and I came across this formula

angle = 38

length = 120

formula

length * sin( angle )

now I have look around for the understanding about this formula and tested the formula my self

0.29636857870938531739229664984902

120 * sin( 38 )

0.29636857870938531739229664984902

sin( 38 )

And as you can see they both calculate the same number, Why is this and what would be the point in using this formula.
