Expert Answer:

From the log table find the value of sin 410 which will be the value ofsin r in the formula

put this value  and the value of refractive index 'n' in the formula

n = sin i/sinr

Now  the value of sin i after converting in degres with the help of log table will give you the desired angle of incidence.
