basic trigonometry
How is sin (90+theta) is X/r
When this angle is not making a useful triangle?
Thanks

Note for OP
+solved @user to close the thread when your doubt is solved. Mention the user who helped you solve the doubt. This will be added to their stats.sin(90+theta) is cos theta
and then cos theta is x/r
Bro I know that but I am just asking for concept that sin(90+theta) se X/R kese aya?
The teacher derived this formula so I am confused in derivation
bhai vo to express karne ka tarika hai, sin(90+theta) = cos theta
which in turn is equal to x/r
hence, its written like that
gaurav can you elaborate your doubt? or is this sorted?
