    Alright given the angles: A=30 B=60 *(180-90-30)* C=90 Given the sides: a=5 Use the Law of Sines: Lengh AC also known as b b= 5/sin(30 (sin(60) b= 8.66

    Sorry, but still don't understand. So, the lengh of AC =8.66. Should that # be rounded because that # is not in the answers?

    Let me double check something...Did the problem give you the degrees for Angle A and C? If so then according to the Law of Sines length of AC would be 8.66 or something withing reasonable range...like 9.
