Finding velocity components for a projectile at 40 degrees

[souzky21]

Homework Statement

A golfball is hit with a velocity of 25m/s at an angle of 40 degrees above the horizontal. What are the horizontal and vertical components of the velocity?

i don't want the answer that's not my objective... just the correct formula cause I've been using all these mathematic equations which are getting me nowhere
