Answer:
n=2.053
Explanation:
We will use Snell's Law defined as:
Where n values are indexes of refraction and 
values are the angles in each medium. For vacuum, the index of refraction in n=1. With this we have enough information to state:
Solving for 
yields:
Remember to use degrees for trigonometric functions instead of radians!
