Hello,
I have read about Euler's angles and matrices, including zxz,zyz, etc . I am not obliged to use a specific rotation but rather I want to figure out what angles I need to use for alpha,theta, gamma in the specific matrix. For example, I have a vector from the centre with vertex x,y,z of (0,0,15), I want to rotate it to (3,12,15), what angles should I use or how can I obtain these angles ? If let's say I choose zyz, i am finding difficulties finding the corresponding angles after the first xy plane rotation. Please disregard the scaling factor and just consider the orientation. Look forward to hearing from you

Use quaternion to Euler convertion. Doing a search in Google will produce hundreds of examples. Here are just a few...
