Respuesta :
Sin/Cos if that's one of the answers. you have to use trig because you must resolve into components.
Answer
Sine and Cosine
Explanation
For the vertical and the horizontal forces the component is zero. If the only the horizontal and the vertical forces are given and you want to find the force at a given angle, you calculate the component forces.
To find the component forces you apply the trigonometric functions sine and cosine.
