Question set position relative to angle in 2d

hello, let's say my enemy is 37 degrees and 15m from my player. is there a way to set it so let's say his y is 0.7 and his x is 0.8, so the angle between then will be 37 degrees?
soory for bad english.

Code (csharp):

1. var myEnemyPos = atDistance(15f, toCartesian(toRadians(37f)));

where

Code (csharp):

1. Vector3 atDistance(float distance, Vector3 direction) => distance * direction;
2. float toRadians(float angle) => angle * Mathf.Deg2Rad;
3. Vector3 toCartesian(float radians) => new Vector3(MathF.Cos(radians), MathF.Sin(radians), 0f);

To understand this learn more about unit circle and radians, as well as vectors and directions. There are plenty of resources online.

Same code, more compactly

Code (csharp):

1. var radians = angle * Mathf.Deg2Rad;
2. var myEnemyPos = 15f * new Vector3(MathF.Cos(radians), MathF.Sin(radians), 0f);

The solution is on the XY plane. For XZ plane, obviously switch the arguments around.
