Please help me with this question.

n = 1.4 n, =1.7 B A d = 10 cm d =15 cm Figure 2: Picture of the setup in problem 2. 2.) Two parallel-sided blocks of glass of refraction index n1 = 1.4 and n2 = 1.7 lie next to each other as shown above. A light ray strikes the first one at an incident angle of 40. (a.) Calculate the angle of refraction 0 as the ray emerges from the second block to air. (b. ) Calculate the distance AB, where B is the point of exit
