In triangle MPN, where ∠M = 60°, ∠P = 40°, and MN = 7 cm, what is the length of PN using the Law of Sines?
a) The sine of 27 degrees divided by PN equals the sine of 135 degrees divided by 9.5
b) The sine of 27 degrees divided by 9.5 equals the sine of 135 degrees divided by PN
c) The sine of 27 degrees divided by 9.5 equals the sine of 20 degrees divided by PN
d) The sine of 27 degrees divided by PN equals the sine of 20 degrees divided by 9.5
