2/3 of the angle between the incident and reflected beams is 80 degrees. Determine what the angle of reflection is.

We need to find what the angle of reflection of the incident ray is if we initially know that 2/3 of the degree between the angle of incidence and reflection is 80 °.

First, let’s find what the entire angle between the incident and the reflected ray is equal to. To do this, we divide the degree measure 80 ° by 2/3.

So, we get as a result:

80: 2/3 = 80 * 3/2 = 240/2 = 120 ° the whole angle between the reflected and incident rays.

Let’s remember that the angle of reflection is always equal to the angle of incidence.

Looking for the angle of reflection:

120 °: 2 = 60 °.
