Answer:
N represent 5 games
Step-by-step explanation:
Firstly, we need to get the total number of games. From the information given, the total number of games is 9 + N = (9 + N) games
The total number of games won is (2 + N) games and this is exactly half of the total number of games.
This mathematically means
2(2 + N) = (9 + N)
4 + 2N = 9 + N
2N - N = 9 - 4
N = 5 games

Answer:
θ = 36.94°
Step-by-step explanation:
Brewster's law for polarization states that; tan(θ_p) = n2/n1
Where ;
θ_p is the polarizing angle
n1 is the index of refraction of first material
n2 is the index of refraction of second material
Now, our first material here is air while second material is water.
Index of refraction of water = 1.33 while index of refraction of air is 1
Thus,
tan(θ_p) = n2/n1 = 1.33/1
tan(θ_p) = 1.33
(θ_p) = tan^(-1)1.33
(θ_p) = 53.06°
Now, polarizing angle is the angle of incidence for which all the reflected light is polarized and it's above the vertical. Thus to get the angle to the horizontal, it will be;
θ = 90° - (θ_p) = 90° - 53.06° = 36.94°
