150 degrees
angle made by ray on mirror = 15
angle made by ray with the normal (angle of inc.) = 90 -15
= 75
angle of ref. = 75
angle between inci. & ref. rays = 75 + 75
= 150 degrees

Often the angle of incidence of a light ray is measured from the normal of the surface that is a perpendcular ray from the point of incidence. If the ray is 15° from that, the reflected ray will be 30° away. If it is 15 degrees from the plane of the surface of the mirror the reflected ray will be 150° away.

incident ray strikes at 15 degree to mirror
hence it makes an angle of 90-15=75 degree with normal to the mirror
so angle of reflection=75 degree with normal
so angle between incident and reflected ray=150 degree

All you need to know here is the incident angle and the reflected angle are same with respect to the vertical axis to the mirror plane. You do the math

If the mirror is flat, and you're talking 15 degrees from perpendicular, then the reflected ray would be 30 degrees from the incident ray.
If you're talking 15 degrees from parallel, then the above answer would be correct.
'nuff said?

no matter where i set the reflection to start, it is a 90 degree regardless, between the incident ray and reflected ray

If you measure your angle relative to the normal of the mirror, the angle will be 30 degrees.
But if you measure your angle relative to the surface of the mirror, the angle will be 150.
See you

90 degrees if the mirror is flat.
