Triangle PQR has side P across from angle P, side Q across from angle Q, and side R across from angle R. If ∠P measures 27°, ∠R measures 135°, and R equals 9.5, what equation represents the length of side P using only the Law of Sines?
a) The sine of 27 degrees divided by P 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 P
c) The sine of 27 degrees divided by 9.5 equals the sine of 20 degrees divided by P
d) The sine of 27 degrees divided by P equals the sine of 20 degrees divided by 9.5
