Angle of incidence = 90-40=50 degrees
Angle of reflection =angle of incidence =50 degrees

Hope this helps... Plz Mark it as the brainliest...

As you see in the figure, Angle of incidence (i) is complementary (lies between 90 degrees) to the given angle,that is complement of i (denoted by i`)
So, the value of angle of incidence is 90-40=50 degrees.

Now, angle of refraction(r) is approximately ~ = i 
.'. r=i=50.

Hope it would prove helpful to you.Thanks!
