How to split velocity into two smaller vectors at a chosen degree?
What I want is to go from a velocity of a rigidbody and then split that velocity into two smaller velocity's that go roughly the same way just at a higher or lower angle. I tried using SohCahToa but it only worked when the object was going a specific direction. The black arrow is the velocity and the red is what I want to find. Thanks.

You can rotate a Vector by multiplying it with a Quaternion. For example:
Quaternion rotA = Quaternion.AngleAxis(30f, Vector3.forward);
Quaternion rotB = Quaternion.AngleAxis(-30f, Vector3.forward);
// Don't know what you're using, so I'm guessing Vector3
Vector3 baseVelocity = rb.velocity;
// Halving them to give each new vector a lesser magnitude
Vector3 halfVelA = rotA * baseVelocity * 0.5f;
Vector3 halfVelB = rotB * baseVelocity * 0.5f;
