answer should be 15°, if we take 60° given in the question as the angle between incdnt ray and mirror, then it will give 30° as the tilted angle.... i hope it will help

wrong answer
yes, there is confusion that 60° is which angle-angle with normal or mirror
theta is angle between normal and incidence
if 60 is angle b/w incident ray and normal then 15 is the right ans
