1) Use Snell's law
n1sin1 = n2sin2
sin2 = n1 sin1 / n2
2 = arcsin (1 * sin 45 / 1.52)
2 =27.7 degree
-------------------------------------------------------
2)
Use Snell's law
n1sin1 = n2sin2
sin2 = n1 sin1 / n2
2 = arcsin ( 1 * sin 30 / 1.33)
2 = 22.1 degree
same diagram as above...just change the angles.
