we can use the law of sines to solve this...

sin30 / 4.38 = sin2 / y          (multiply both sides by y)
ysin30 / 4.38 = sin2            (multiply both sides by 4.38)
ysin30 = 4.38sin2                (divide both sides by sin30)
y = 4.38sin2 / sin30
y = .305719                      (change to degrees)
y = 18°
